Description

Spiral rubbing pea peeling machine

technical field

The invention provides a spiral rubbing pea peeling machine, which is applied to the bean starch production industry with peas as the main raw material. Before the peas are crushed, the pea skins are removed first.

Background technique

With the improvement of people's living standards and the diversification of food structure, people pay more and more attention to the palatability, nutrition and health care of food and the rationality of composition. Some low-fat, high-protein foods (such as peas, etc.) are more and more popular. People's favorite. Among them, pea, as a low-fat, high-protein food, has the advantages of low price and various varieties compared with other bean foods, and has been used as the main raw material of the milling industry in recent years.

Bean starch has a wide range of uses in the food industry. It is the main additive for making ham and sausage, and it can also be used for making ice cream and ice cream. Because of its high amylose content, excellent properties such as high thermal viscosity, high gel transparency, and good gel strength, it is a good raw material for preparing vermicelli and vermicelli. Bean starch occupies an important role in the industrial production of vermicelli in many countries in the world. important position.

Vermicelli is a traditional food loved by the Chinese people, with a history of at least 1,400 years in China. Domestic production of vermicelli mainly uses bean starch, such as mung bean, pea, broad bean, adzuki bean and other starches. Among them, mung bean starch is recognized as the best raw material for making vermicelli, but its price is relatively high. Therefore, the use of pea starch as the raw material for making vermicelli has become the first choice, and the separation and extraction of bean starch, physical and chemical properties, rheological properties and their relationship with food quality have also attracted more and more attention from domestic and foreign scientific and technological workers. .

However, in the production process of bean starch, the traditional process of soaking raw materials and crushing them with their skins is generally used at present. As a result, it not only brings a lot of trouble to the subsequent deslagging process, but also the crushed soybean skins have a great impact on the starch quality. Even the quality of fans, such as whiteness and other indicators have a great impact. Therefore, we have developed a planetary rubbing pea peeling machine. The test results show that this machine can remove the pea skin more conveniently, so it has applied for a national invention patent with the application number: 201110224748.6. However, through further experiments, it was found that: the rotation axis of the planetary rubbing pea peeling machine involved in this patent is inclined at an angle to the horizontal plane, which is not conducive to the manufacture and installation of the equipment; within the effective length range of the drum, all planes perpendicular to the axis of the drum The number of kneading rollers in the same plane is equal to the number of planetary shafts, that is, the kneading rollers on different planetary shafts are divided into multiple groups and located in each plane perpendicular to the axis of the drum, so that the kneading rollers in the same plane repeatedly knead the same rollers in the drum. One position; the soaked peas are still relatively loose, and the peeling effect will not be affected even without stirring.

Looking at the current situation of the bean starch industry, there is an urgent need for a device that can easily remove the pea skin, has a simpler structure and has a better peeling effect, so as to simplify the subsequent deslagging process and improve the quality of starch and vermicelli.

Said spiral rubbing pea peeling machine, the driving device includes a motor, a belt transmission mechanism and a reducer, the motor is connected to the input end of the reducer after being shifted through the belt transmission mechanism, and the output end of the reducer is connected to the driving shaft.

Its working principle is: the empty sleeve in the middle of the driving shaft of the planetary transmission is supported in the center hole of the fixed sun gear, the middle of the driven shaft is supported in the hole of the bearing I whose axis is coaxial with the driving shaft, the driving shaft and the driven shaft The common axis of the drive shaft is parallel to the horizontal plane, and the outer end of the driving shaft away from the driven shaft is connected to the driving device; the centers of the two planet carriers are respectively fixed on the end of the driving shaft close to the driven shaft and the end of the driven shaft close to the driving shaft. After the planetary shafts pass through the planetary carrier fixed on the driving shaft and are evenly distributed in the circular holes on the same circumference of the planetary carrier, one end close to the driving device is equipped with a planetary wheel meshing with the sun gear, and the other end is supported by an empty sleeve in the center. The planet carrier fixed on the driven shaft is evenly distributed in the circular holes on the same circumference of the planet carrier, and the axis of each planet shaft is parallel to the common axis of the driving shaft and the driven shaft; each planet shaft is fixed with multiple kneading Rollers, the kneading rollers on the adjacent planetary shafts are spaced in the axial direction in sequence along the rotation direction of the planetary carrier by an equal distance that is less than the axial width of the kneading rollers, and according to "one kneading roller for each planetary shaft" According to the principle, a plurality of adjacent kneading rollers equal to the number of planetary shafts form a helical line whose pitch is equal to the number of planetary shafts multiplied by the distance between the kneading rollers on the adjacent planetary shafts along the axial direction; chain drive The two drive shafts of the device are respectively supported in the inner holes of multiple bearings II whose axes are parallel to the drive shaft and symmetrically arranged on both sides below the drive shaft. Multiple brackets are fixed between the bearings II on the two drive shafts. The two ends of the transmission shaft are respectively fixed with sprocket Ⅰ, one sprocket Ⅱ is fixed between the sun gear on the driving shaft and the driving device, and the other sprocket Ⅱ is fixed on the outer end of the driven shaft away from the planet carrier. The two sprockets II are respectively connected with the sprockets I fixed at both ends of the transmission shaft through the chain to form a chain transmission device; the inner surface of the drum body whose diameter is greater than the distance between the two transmission shafts and whose axis is coaxial with the drive shaft is provided with a plurality of Ribs and two ends of the outer circle are respectively provided with rollers supported in the rectangular groove of the roller; the lower part of the feed hopper with the feed gate inside is fixed with a guide groove whose end is inserted into the end of the roller close to the sun wheel. The other end is equipped with an arc-shaped discharge port with an inner diameter slightly larger than the outer circle of the drum.

When the driving device drives the planetary carrier through the driving shaft, and the planetary shaft revolves around the common axis of the driving shaft and the driven shaft, due to the meshing movement between the planetary gear and the sun gear, the planetary gear is forced to drive the planetary shaft to revolve around its own axis. Turn to the same rotation. Therefore, the kneading wheel fixed on the planetary shaft also performs the same rotation as the revolution steering around the planetary shaft axis while revolving with the planetary shaft. At the same time, the driving device also drives the sprocket I fixed at both ends of the drive shaft, the two drive shafts and the idler rollers fixed on the drive shaft through the drive shaft, the sprocket II fixed on the drive shaft and the chain, as a The revolution of the planetary frame turns to the same rotation, thereby further driving the rollers whose two ends are supported in the rectangular groove of the idler roller through the rollers to rotate opposite to the revolution of the planetary frame. In addition, the transmission shaft also drives the sprocket II fixed on the outer end of the driven shaft away from the driving shaft through the sprocket I and the chain fixed at the end close to the driven shaft, and then fixed on the driven shaft through the driving center of the driven shaft. The upper planetary carrier rotates to avoid twisting of each planetary shaft relative to the common axis of the driving shaft and the driven shaft due to the rotational resistance of the kneading roller.

When the soaked peas are fed into the inner chamber of the drum near the end of the driving shaft through the feed hopper, due to the frictional force and centrifugal force between the inner wall of the drum and the effect of centrifugal force, they will rotate together with the drum. Since the revolution and rotation of the kneading roller are opposite to the rotation of the drum, the peas raised to a certain height are squeezed into the wedge-shaped space formed by the elastic kneading claws installed on the kneading roller and the inner wall of the drum. With further rotation, the peas are squeezed between the elastic rubbing claws, the inner wall of the drum and its ribs and rubbed repeatedly. The revolution and rotation movement of the drum will squeeze the peas at the bottom of the drum between the elastic rubbing claws, the inner wall of the drum and its ribs and rub them repeatedly, and lift them to a certain height with the rotation of the rubbing roller. After rubbing, the peas will also The kneaded roller is pushed to both sides along the cylinder axis, and slides down along the inner wall of the cylinder. Because a plurality of kneading rollers on each planetary shaft form a helical line of "the pitch is equal to the number of planetary shafts multiplied by the distance between the kneading rollers on the adjacent planetary shafts along the axial direction", so when a certain kneading roller kneads the peas, And after being pushed to both sides along the cylinder axial direction, the kneading roller at the back is due to a distance less than the axial width of the kneading roller relative to the kneading roller at the front along the cylinder axially The peas in the "ridge" are further rubbed, instead of the front and rear rubbing rollers being in the same plane, repeating the same position where the peas in the rubbing roller have been pushed to both sides. Therefore, the peas are kneaded more times in the drum and evenly and fully, which improves the peeling effect. Simultaneously, since the kneading rollers on each planetary shaft are along the rotation direction of the planetary carrier, they are spaced apart in the axial direction by an equal distance which is less than the axial width of the kneading rollers, and the front and rear kneading rollers still exist in the axial direction of the cylinder. Certain overlapping, so the peas rubbed by each rubbing roller will always be pushed along one and the same direction. In this way, by adjusting the revolution and rotation direction of the planet carrier, the peas can be pushed to the discharge port after being kneaded and pushed for many times after being put into the drum from the feed hopper. Finally, the peas whose peeling rate reaches the requirement flow out from the discharge port.

Compared with the prior art, the present invention can realize multiple kneading, good peeling effect, simpler and more reliable structure, high production efficiency, and can fully meet the production requirements of large-scale starch enterprises.
