Description
Technical Field
The invention relates to a food material processing technology, in particular to a quick pulping method of a food processing machine.
Background
Commercial food processors typically include a base and a blender cup mounted to the base. A crushing knife for crushing food materials is arranged in the stirring cup. The volume of stirring cup is close with the biggest slurrying volume, and the space of stirring cup this moment is less to increase the contact probability of eating material and crushing sword when satisfying the required space of slurrying, promote crushing efficiency. In the pulping process, the food materials need to be heated to a higher temperature to soften the food materials, and then the food materials are crushed, so that the abrasion of the crushing knife is reduced. However, in the process of crushing the food material, the crushing blades need to continuously collide with the food material at a high speed, resulting in an increase in the temperature of the slurry. The temperature of the food material is heated to a higher temperature, and the high-speed collision between the crushing blades and the food material further causes the temperature of the slurry to rise, so that the temperature of the slurry exceeds a limit value. The stirring cup cannot provide more anti-overflow space for the slurry due to the smaller space of the stirring cup, so that the slurry is easy to overflow when the temperature of the slurry exceeds a limit value, and the improvement is needed.
Disclosure of Invention
The invention aims to provide a quick pulping method of a food processor. The pulping method can avoid the overflow of the pulp caused by the temperature of the pulp exceeding the limit value, thereby enabling the pulp to be crushed at high speed in a small space, improving the crushing efficiency and shortening the pulping time.
The technical purpose of the invention is realized by the following technical scheme:
a quick pulping method of a food processor comprises the following steps:
presetting a temperature control range during slurry crushing, wherein the lower limit of the temperature control range is a first preset temperature T1, and the upper limit of the temperature control range is a second preset temperature T2;
heating the food material and water to a temperature of the slurry not lower than a first preset temperature T1;
maintaining the temperature of the slurry by using heat generated by crushing the food material;
when the temperature of the slurry reaches the second preset temperature T2 or tends to reach the second preset temperature T2, cooling the slurry so that the temperature of the slurry is not higher than the second preset temperature T2;
wherein the first preset temperature T1, the second preset temperature T2 and the boiling point temperature T satisfy T-10 ≤ T1 < T2 < T.
By adopting the technical scheme, the first preset temperature T1 and the second preset temperature T2 are not lower than the boiling point temperature by less than 10 ℃, so that the first preset temperature T1 and the second preset temperature T2 both belong to a high temperature range. The temperature of the slurry can be maintained by the heat generated by crushing the food materials, and the heat generated by crushing the food materials is not less than the heat lost by the heat exchange between the slurry and the outside. Crushing food materials can generate such high heat, and the food materials need to be in a high-speed crushing state.
Reaching the second preset temperature T2 is higher than or equal to the second preset temperature T2. The tendency to reach the second preset temperature T2 means that the slurry temperature tends to reach the second preset temperature T2 while maintaining the current conditions, but the second preset temperature T2 is not reached yet. When the temperature of the slurry reaches the second preset temperature T2 or tends to reach the second preset temperature T2, the slurry is cooled so that the temperature of the slurry is not higher than the second preset temperature T2. At the moment, the upper limit of the actual temperature range is slightly higher than the second preset temperature T2 or even not higher than the second preset temperature T2 when the pulp is controlled to be crushed, so that the situation that the pulp overflows due to the fact that the temperature of the pulp exceeds the limit value is avoided, the pulp can be crushed at high speed in a small space, the crushing efficiency is improved, and the pulping time is shortened.
The invention is further configured to: the difference between the upper limit and the lower limit of the temperature control range is delta T, the pulping amount of the food processor is L, the crushing rotating speed is V, and delta T L/V is more than or equal to 0.03 and less than or equal to 3.
By adopting the technical scheme, the initial temperature of the slurry is assumed to be in the temperature control range. When the slurry amount L is constant, the higher the pulverization rotation speed V is, the faster the temperature rise speed of the slurry becomes. Therefore, if Δ T is kept constant, the slurry is likely to exceed the temperature control range due to an excessively high temperature rise rate. Although the slurry temperature returns to the temperature control range after being cooled, the temperature rise speed is too fast to exceed the temperature control range again. Therefore, the slurry needs to be cooled frequently, which affects the normal processing of the slurry, reduces the grinding efficiency, and prolongs the grinding time. Therefore, when the grinding rotational speed V is increased, in order to avoid the need to frequently cool the slurry due to an excessively high slurry temperature rise rate, Δ T and the grinding rotational speed V are in a proportional relationship such that Δ T can be increased as the grinding rotational speed V is increased.
When the crushing rotating speed V is constant, the larger the pulping amount L is, the larger the pulping amount is, and the lower the temperature rise speed of the pulp is. Therefore, when the slurry amount L is increased, the slurry is not easy to exceed the temperature control range because the temperature rise speed is too high. The smaller the Δ T, the more accurate the slurry temperature can be controlled. Therefore, in order to enable more accurate slurry control when the amount of slurry L is increased, Δ T and the amount of slurry L form an inverse relationship such that Δ T can be decreased as the amount of slurry L is increased.
If Δ T is constant, Δ T × L/V > 3 means that L is too large and V is too small. And a larger pulp amount L means a larger crushing load. An excessively small pulverizing rotational speed V means that the pulverizing power is weak. When the grinding load is large and the grinding power is weak, the food processor is difficult to grind. If Δ T × L/V < 0.03, it means that L is too small and V is too large, and at this time, the temperature rise rate of the slurry is too high, and the slurry needs to be cooled frequently, which affects the normal processing of the slurry, reduces the pulverization efficiency, and prolongs the pulverization time. Therefore, the delta T/V is not less than 0.03 and not more than 3, the crushing load and the crushing power of the food processor are matched, the food processor can crush fully, the frequency of cooling the slurry is reduced, the crushing efficiency is improved, and the crushing time is shortened.
The invention is further configured to: the difference value between the boiling point temperature T and the upper limit of the temperature control range is delta T, the pulping amount of the food processor is L, the crushing rotating speed is V, and delta T L/V is more than or equal to 0.05 and less than or equal to 4.5.
By adopting the technical scheme, when the pulping amount L is constant, the higher the crushing rotating speed V is, the faster the temperature rising speed of the pulp is. Therefore, if Δ T is kept constant, the slurry is likely to reach the boiling point temperature T due to an excessively high temperature rise rate in the period from when the detected slurry temperature reaches the cooling condition to when cooling is effected, and the slurry is likely to overflow. Therefore, when the grinding rotational speed V is increased, overflow due to insufficient cooling due to an excessively high slurry temperature rise rate is avoided. Δ t and the pulverization rotation speed V form a proportional relationship so that Δ t can be increased as the pulverization rotation speed V increases.
When the crushing rotation speed V is constant, the larger the pulping amount L is, the larger the pulping amount is, and the slower the temperature rise speed of the pulp is. Therefore, when the slurry amount L is increased, the slurry is not easy to exceed the temperature control range because the temperature rise speed is too high. The smaller Δ T, the closer the slurry temperature approaches the boiling temperature T, making the slurry more mellow. Therefore, in order to raise the slurry temperature as much as possible when the amount of slurry L increases, Δ t and the amount of slurry L form an inverse relationship such that Δ t can be reduced as the amount of slurry L increases.
At a constant Δ t, if Δ t × L/V > 4.5, it means that L is too large and V is too small. And an excessively large amount of pulp L means a larger crushing load. An excessively small pulverizing rotational speed V means that the pulverizing power is weak. When the grinding load is large and the grinding power is weak, the food processor is difficult to grind. If Δ T L/V < 0.05, it means that L is too small and V is too large, and at this time, the temperature rise rate of the slurry is too fast, and the slurry easily reaches the boiling point temperature T due to the too fast temperature rise rate, resulting in overflow of the slurry. Therefore, the delta T L/V is not less than 0.05 and not more than 4.5, the crushing load and the crushing power of the food processor are matched, the food processor can crush fully, and the phenomenon that the slurry overflows due to the fact that the slurry reaches the boiling point temperature T due to the fact that the temperature rise speed is too high can be avoided.
The invention is further configured to: the actual temperature range includes free section and cooling segment when thick liquid is smashed, when thick liquid temperature is located the free section, rises thick liquid temperature to the cooling segment to the heat that food material smashed the production, when thick liquid temperature is located the cooling segment, cools off thick liquid in order to reduce thick liquid temperature to the free section.
The invention is further configured to: when the slurry needs to be cooled so that the temperature of the slurry is not higher than the second preset temperature T2, one of the following ways is selected:
continuing to crush the slurry, and cooling the slurry until the temperature of the slurry is not higher than a second preset temperature T2; or stopping the pulverization, and cooling the slurry until the temperature of the slurry is not higher than the second preset temperature T2.
By adopting the technical scheme, the slurry can be continuously crushed while being cooled, so that the crushing efficiency is improved, and the crushing time is shortened; the crushing can also be stopped, and the phenomenon that the slurry overflows due to continuous crushing in the period from the detection of the temperature of the slurry reaching the cooling condition to the cooling effect is avoided.
The invention is further configured to: when the slurry needs to be cooled so that the temperature of the slurry is not higher than the second preset temperature T2, the crushing rotating speed V is reduced to continue crushing, and then the slurry is cooled until the temperature of the slurry is not higher than the second preset temperature T2.
Through adopting above-mentioned technical scheme, compare in stopping smashing, reduce crushing rotational speed V and can play the crushing effect to can improve crushing efficiency, shorten crushing time. Reducing the pulverizing rotational speed V can reduce the possibility of slurry overflow, as compared with pulverizing while maintaining the pulverizing rotational speed V unchanged.
The invention is further configured to: the maximum pulping amount of the food processor is L1, the volume of the food processor is L2, and L1/L2=0.8-1: 1.
By adopting the technical scheme, the maximum pulping amount of the food processor is close to the volume, so that the space of the stirring cup is small, and the stirring cup cannot provide a space for preventing more slurry from overflowing, thereby avoiding the condition that the temperature of the slurry exceeds the limit value in the pulping process to cause the overflow of the slurry.
The invention is further configured to: the temperature of the slurry is maintained to be not lower than a first preset temperature T1 by utilizing the heat generated by crushing the food material; or when the temperature of the slurry reaches the first preset temperature T1 or tends to reach the first preset temperature T1, the slurry is heated so that the temperature of the slurry is not lower than the first preset temperature T1.
Through adopting above-mentioned technical scheme, the heat that utilizes food material to smash the production is not less than the thick liquid and the external heat lost that carries out the heat exchange to can maintain the thick liquid temperature and be not less than first preset temperature T1. Reaching the first preset temperature T1 means being lower than or equal to the first preset temperature T1. The tendency to reach the first preset temperature T1 means that the slurry temperature tends to reach the first preset temperature T1 while maintaining the current conditions, but the slurry temperature has not yet reached the first preset temperature T1. When the slurry is cooled, the cooling width may be excessively large. At this time, the amount of heat generated by the crushing of the food material is not enough to maintain the slurry temperature not lower than the first preset temperature T1, resulting in the slurry temperature reaching or tending to reach the first preset temperature T1. At this time, the slurry needs to be heated to maintain the temperature of the slurry within the temperature control range, so as to ensure the mouthfeel of the slurry.
The invention is further configured to: when the temperature of the slurry reaches the first preset temperature T1 or tends to reach the first preset temperature T1, the slurry is heated while keeping the pulverization rotation speed V constant so that the temperature of the slurry is not lower than the first preset temperature T1.
By adopting the technical scheme, when the slurry is heated, the slurry is continuously heated without overflowing. If the crushing rotating speed V is increased, the temperature rising speed of the slurry can be accelerated, so that the crushing rotating speed V needs to be reduced after the temperature of the slurry enters a temperature control range to avoid the too high temperature rising speed. The crushing rotation speed V changes between acceleration and deceleration, and the service life is easily influenced. Therefore, when the slurry is heated, the influence on the service life can be reduced without causing the slurry to overflow by keeping the pulverization rotation speed V constant.
The invention is further configured to: food preparation machine includes the frame and installs the stirring cup on the frame, is formed with the crushing chamber that holds edible material and water in the stirring cup, and the stirring cup is provided with the anti-overflow electrode that stretches into crushing chamber, and the boiling temperature is the temperature when gathering thick liquid and touching anti-overflow electrode when boiling the thick liquid.
By adopting the technical scheme, the boiling point temperatures of the serous fluid of different food materials are different. The temperature when the slurry touches the anti-overflow electrode is taken as the boiling point temperature of the slurry, so that the food material applying device can be applied to all food materials. And in the process of boiling the serous fluid, the serous fluid stops heating after touching the anti-overflow electrode, and continues heating after leaving the anti-overflow electrode. Therefore, in the boiling process, the serous fluid can touch the anti-overflow electrode for a plurality of times. The temperature when the thick liquid that gathers touches anti-overflow electrode when boiling thick liquid is regarded as boiling point temperature T, and is comparatively accurate.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
Referring to fig. 1, a method for rapidly preparing milk by a food processor includes the following steps:
presetting a temperature control range during slurry crushing, wherein the lower limit of the temperature control range is a first preset temperature T1, and the upper limit of the temperature control range is a second preset temperature T2;
heating the food material and water to a temperature of the slurry not lower than a first preset temperature T1;
maintaining the temperature of the slurry by using heat generated by crushing the food material;
when the temperature of the slurry is higher than the second preset temperature T2, the crushing is stopped, and then the slurry is cooled so that the temperature of the slurry is not higher than the second preset temperature T2. Stopping crushing to avoid overflowing of the slurry caused by continuous crushing in the period from the detection of the temperature of the slurry reaching the cooling condition to the cooling effect;
generally, the temperature of the slurry is maintained not lower than the first preset temperature T1 by the heat generated by crushing the food material. However, when the slurry is cooled, the cooling amplitude may be too large, so that the temperature of the slurry is cooled to be lower than the first preset temperature T1. At this time, the grinding rotation speed V is kept unchanged, and the pulp is heated so that the temperature of the pulp is not lower than the first preset temperature T1, and the taste of the pulp is guaranteed. When the slurry is heated, the slurry is continuously heated without causing the slurry to overflow. If the crushing rotating speed V is increased, the temperature rising speed of the slurry can be accelerated, so that the crushing rotating speed V needs to be reduced after the temperature of the slurry enters a temperature control range to avoid the too high temperature rising speed. The crushing rotation speed V changes between acceleration and deceleration, and the service life is easily influenced. Therefore, when the slurry is heated, the influence on the service life can be reduced without causing the slurry to overflow by keeping the pulverization rotation speed V constant.
Wherein the first preset temperature T1, the second preset temperature T2 and the boiling point temperature T satisfy T-10 ≤ T1 < T2 < T. Preferably, T1= T-5, T2= T-3, all in degrees c.
The first preset temperature T1 and the second preset temperature T2 are not lower than the boiling point temperature by less than 10 ℃, so that the first preset temperature T1 and the second preset temperature T2 both belong to a high temperature range. The heat generated by crushing the food material can maintain the temperature of the slurry to be not lower than the first preset temperature T1, and the heat generated by crushing the food material is not less than the heat lost by heat exchange between the food material and the outside. Crushing food materials can generate such high heat, and the food materials need to be in a high-speed crushing state.
When the temperature of the slurry is higher than the second preset temperature T2, the slurry is cooled so that the temperature of the slurry is not higher than the second preset temperature T2. At the moment, the upper limit of the actual temperature range is slightly higher than the second preset temperature T2 or even not higher than the second preset temperature T2 when the pulp is controlled to be crushed, so that the situation that the pulp overflows due to the fact that the temperature of the pulp exceeds the limit value is avoided, the pulp can be crushed at high speed in a small space, the crushing efficiency is improved, and the pulping time is shortened.
The food processor comprises a base and a stirring cup arranged on the base, wherein a crushing cavity for containing food materials and water is formed in the stirring cup. The maximum pulping amount of the crushing cavity is L1, the volume of the crushing cavity is L2, and L1/L2=0.8-1: 1. Preferably, L1/L2=1: 1. The maximum pulping amount of the crushing cavity is close to the volume, so the space of the stirring cup is small, and the stirring cup cannot provide a space for preventing overflow of the pulp, and the pulp is required to be prevented from overflowing due to the fact that the temperature of the pulp exceeds a limit value in the pulping process. The stirring cup is provided with an anti-overflow electrode extending into the crushing cavity.
The process of heating the food material and water to a slurry temperature not lower than the first preset temperature T1 is as follows: adding water into food materials, heating the food materials and the water to a serous fluid temperature of T0 by heating power P0, crushing the food materials, heating the food materials by heating power P1 until the serous fluid touches the anti-overflow electrode, and decocting by heating power P2 until the serous fluid temperature is not lower than a first preset temperature T1. Wherein, P0 is more than P1 is more than P2, and T0= T-5 ℃. In the process of boiling the serous fluid, the serous fluid stops heating after touching the anti-overflow electrode and continues heating after leaving the anti-overflow electrode. And collecting the average temperature of the slurry in the boiling process when the slurry touches the anti-overflow electrode as the boiling point temperature T. The boiling point temperature of the slurry of different food materials is different. The temperature when the slurry touches the anti-overflow electrode is taken as the boiling point temperature of the slurry, so that the food material applying device can be applied to all food materials. In the boiling process, the serous fluid can touch the anti-overflow electrode for many times. The temperature when the thick liquid that gathers touches anti-overflow electrode when boiling thick liquid is regarded as boiling point temperature T, and is comparatively accurate. The crushing speed is 2000-4000rpm, so as to break the outer skin of the food material and accelerate the curing.
The difference between the upper and lower limits of the temperature control range is Δ T, Δ T = T2-T1. Preferably, Δ T =2 ℃. The pulping amount of the food processor is L, the crushing rotating speed is V, and delta T L/V is more than or equal to 0.03 and less than or equal to 3. L may be 200, 400, 600, 800, 1000, 1200mL, V may be 8000, 10000, 12000 rpm. The initial temperature of the slurry is assumed to be within the temperature control range. When the slurry amount L is constant, the higher the pulverization rotation speed V is, the faster the temperature rise speed of the slurry becomes. Therefore, if Δ T is kept constant, the slurry is likely to exceed the temperature control range due to an excessively high temperature rise rate. Although the slurry temperature returns to the temperature control range after being cooled, the temperature rise speed is too fast to exceed the temperature control range again. Therefore, the slurry needs to be cooled frequently, which affects the normal processing of the slurry, reduces the grinding efficiency, and prolongs the grinding time. Therefore, when the grinding rotational speed V is increased, in order to avoid the need to frequently cool the slurry due to an excessively high slurry temperature rise rate, Δ T and the grinding rotational speed V are in a proportional relationship such that Δ T can be increased as the grinding rotational speed V is increased.
When the crushing rotating speed V is constant, the larger the pulping amount L is, the larger the pulping amount is, and the lower the temperature rise speed of the pulp is. Therefore, when the slurry amount L is increased, the slurry is not easy to exceed the temperature control range because the temperature rise speed is too high. The smaller the Δ T, the more accurate the slurry temperature can be controlled. Therefore, in order to enable more accurate slurry control when the amount of slurry L is increased, Δ T and the amount of slurry L form an inverse relationship such that Δ T can be decreased as the amount of slurry L is increased.
If Δ T is constant, Δ T × L/V > 3 means that L is too large and V is too small. And a larger pulp amount L means a larger crushing load. An excessively small pulverizing rotational speed V means that the pulverizing power is weak. When the grinding load is large and the grinding power is weak, the food processor is difficult to grind. If Δ T × L/V < 0.03, it means that L is too small and V is too large, and at this time, the temperature rise rate of the slurry is too high, and the slurry needs to be cooled frequently, which affects the normal processing of the slurry, reduces the pulverization efficiency, and prolongs the pulverization time. Therefore, the delta T/V is not less than 0.03 and not more than 3, the crushing load and the crushing power of the food processor are matched, the food processor can crush fully, the frequency of cooling the slurry is reduced, the crushing efficiency is improved, and the crushing time is shortened. The difference between the boiling point temperature T and the upper limit of the temperature control range is Δ T, Δ T = T-T2. Preferably, Δ t =3 ℃. The pulping amount of the food processor is L, the crushing rotating speed is V, and delta t L/V is more than or equal to 0.05 and less than or equal to 4.5. L may be 200, 400, 600, 800, 1000, 1200mL, V may be 8000, 10000, 12000 rpm. When the slurry amount L is constant, the higher the pulverization rotation speed V is, the faster the temperature rise speed of the slurry becomes. Therefore, if Δ T is kept constant, the slurry is likely to reach the boiling point temperature T due to an excessively high temperature rise rate in the period from when the detected slurry temperature reaches the cooling condition to when cooling is effected, and the slurry is likely to overflow. Therefore, when the grinding rotational speed V is increased, overflow due to insufficient cooling due to an excessively high slurry temperature rise rate is avoided. Δ t and the pulverization rotation speed V form a proportional relationship so that Δ t can be increased as the pulverization rotation speed V increases.
When the crushing rotation speed V is constant, the larger the pulping amount L is, the larger the pulping amount is, and the slower the temperature rise speed of the pulp is. Therefore, when the slurry amount L is increased, the slurry is not easy to exceed the temperature control range because the temperature rise speed is too high. The smaller Δ T, the closer the slurry temperature approaches the boiling temperature T, making the slurry more mellow. Therefore, in order to raise the slurry temperature as much as possible when the amount of slurry L increases, Δ t and the amount of slurry L form an inverse relationship such that Δ t can be reduced as the amount of slurry L increases.
At a constant Δ t, if Δ t × L/V > 4.5, it means that L is too large and V is too small. And an excessively large amount of pulp L means a larger crushing load. An excessively small pulverizing rotational speed V means that the pulverizing power is weak. When the grinding load is large and the grinding power is weak, the food processor is difficult to grind. If Δ T L/V < 0.05, it means that L is too small and V is too large, and at this time, the temperature rise rate of the slurry is too fast, and the slurry easily reaches the boiling point temperature T due to the too fast temperature rise rate, resulting in overflow of the slurry. Therefore, the delta T L/V is not less than 0.05 and not more than 4.5, the crushing load and the crushing power of the food processor are matched, the food processor can crush fully, and the phenomenon that the slurry overflows due to the fact that the slurry reaches the boiling point temperature T due to the fact that the temperature rise speed is too high can be avoided.
The actual temperature range during slurry crushing comprises a heating section, a free section and a cooling section. When the slurry temperature is in the heating section, the food material is heated to raise the slurry temperature to the free section. When the temperature of the slurry is in the free section, the temperature of the slurry is raised to the cooling section by the heat generated by crushing the food material. When the slurry temperature is in the cooling section, the slurry is typically cooled to reduce the slurry temperature to the free section, but there is also the potential to reduce the slurry temperature to the heating section.
The specific way of cooling the slurry may be to add water below the second preset temperature T2 to the slurry, or to cool the slurry by using a cooling plate. Preferably, the slurry is cooled by adding water to the slurry at a temperature lower than the second predetermined temperature T2, and the temperature of the water lower than the second predetermined temperature T2 is preferably normal temperature.
The specific way of heating the slurry can be to add water higher than the first preset temperature T1 into the slurry, or to heat the slurry by using a heating pipe. Preferably, the slurry is heated using a heated tube.
If the slurry is cooled by the refrigerating sheet, the existing food processing machine needs to be additionally provided with the refrigerating sheet, so that the cost is increased. Meanwhile, the refrigerating efficiency is low when the refrigerating sheet starts to work. The slurry needs to be cooled, which means that the slurry is about to overflow, and the excessive slow refrigerating efficiency of the refrigerating sheet causes the temperature of the slurry to exceed the limit value, so that the slurry overflows. If the slurry is heated by using water higher than the first preset temperature T1, the normal temperature water stored in the existing food processor needs to be heated first, which means that a heating module for heating the normal temperature water needs to be added on the basis of the existing food processor, and the cost is increased. The slurry is cooled by normal temperature water, and is heated by the heating pipe, so that the process can be finished by depending on the conventional food processing machine, and the cost is low. Simultaneously, adopt normal atmospheric temperature water to cool off the thick liquid, as long as normal atmospheric temperature water and thick liquid contact can play the effect of cooling off the thick liquid to can reduce the thick liquid temperature fast, avoid the thick liquid to spill over.
Example 2
Example 2 differs from example 1 in the timing of cooling and heating the slurry.
In example 2, when the slurry temperature tends to reach the second preset temperature T2, the slurry is cooled so that the slurry temperature is not higher than the second preset temperature T2. When the slurry temperature tends to reach the first preset temperature, the slurry is heated so that the slurry temperature is not lower than the first preset temperature T1. The tendency to reach the second preset temperature T2 means that the slurry temperature tends to reach the second preset temperature T2 while maintaining the current conditions, but the second preset temperature T2 is not reached yet. The tendency to reach the first preset temperature T1 means that the slurry temperature tends to reach the first preset temperature T1 while maintaining the current conditions, but the slurry temperature has not yet reached the first preset temperature T1.
Example 3
Example 3 differs from example 1 in the grinding rotational speed V at which the slurry is cooled.
In example 3, when the slurry temperature is higher than the second preset temperature T2, the pulverization rotation speed V is lowered, and the slurry is cooled so that the slurry temperature is not higher than the second preset temperature T2. Preferably, the reduced milling rotation speed V is 1/2 of the pre-reduction milling rotation speed V. Compared with stopping crushing, the crushing device has the advantages that the crushing effect can be achieved by reducing the crushing rotating speed V, so that the crushing efficiency can be improved, and the crushing time can be shortened. Reducing the pulverizing rotational speed V can reduce the possibility of slurry overflow, as compared with pulverizing while maintaining the pulverizing rotational speed V unchanged.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
