Background

Most of the existing sterilization methods are to sterilize sterilized materials in sealed and packaged food in a high-pressure container in a high-temperature manner so as to eliminate target bacteria in the sterilized materials, thereby achieving the purposes of prolonging the shelf life of the food and being beneficial to expanding the sales range.

The high-temperature sterilization is mainly carried out in the sterilization kettle, the sterilization process comprises the steps of putting food into the sterilization kettle, then closing the sterilization kettle, introducing high-temperature steam into the sterilization kettle, pressurizing the sterilization kettle to enable the sterilization kettle to be in a high-temperature and high-pressure state, and maintaining the pressure for a period of time to take the food out. When taking out food, in order to ensure safety, the sterilization kettle is cooled firstly to condense steam, so that the pressure in the sterilization kettle is reduced, and then the sterilization kettle can be opened to take out the food.

Therefore, after the sterilization kettle performs sterilization, the steam in the sterilization kettle still has residual heat, and after the sterilization is finished, the steam in the sterilization kettle is directly condensed, so that the utilization rate of heat energy is lower.

The invention aims to provide a food cleaning and processing device with high heat energy utilization rate.

In order to achieve the above purpose, the basic scheme of the invention is as follows:

the food cleaning and processing device comprises a sterilizing cylinder body, a steam chamber, a conveying part and a lifting mechanism, wherein the sterilizing cylinder body is vertically arranged, the top of the sterilizing cylinder body is provided with a heating device and a temperature sensor, a sealing plate and a bearing plate are connected in the sterilizing cylinder body in a sliding manner, the sealing plate is positioned above the bearing plate, a conical hole with the lower end larger than the upper end is arranged on the sealing plate, a frustum matched with the conical hole is connected on the sealing plate in a sliding manner, and a pull rope with one end connected with the conical platform and the other end connected with the top of the sterilizing cylinder body; the lifting mechanism is connected with the bearing plate, the bearing plate can slide up and down in the sterilizing cylinder body through the lifting mechanism, and a support column is arranged on the bearing plate; the lower part of the sterilizing cylinder body is provided with a feeding hole and a discharging hole which are oppositely arranged, the conveying belt comprises a feeding part and a discharging part, the feeding part corresponds to the feeding hole, and the discharging part corresponds to the discharging hole; the upper end of the sterilizing cylinder body is provided with an air inlet, the steam chamber is communicated with the sterilizing cylinder body through the air inlet, a pneumatic control valve is arranged in the steam chamber, and the opening and closing of the pneumatic control valve are controlled by the pressure in the sterilizing cylinder body.

The principle of the food cleaning and processing device of the scheme is as follows:

the food to be sterilized is placed on the conveying part, and then the food is continuously conveyed on the conveying part. When the lifting mechanism enables the bearing plate to move downwards, the sealing plate moves downwards together with the bearing plate under the action of gravity, the space above the sealing plate is gradually increased, and the pressure is gradually reduced, so that steam between the sealing plate and the bearing plate enters the sealing plate through the taper hole; after the stay cord is straightened, the shrouding will not move down continuing, because the stay cord is connected with the frustum, consequently under the action of gravity, frustum and taper hole cooperation to the upper space and the lower part space of shrouding are kept apart by the shrouding, and consequently steam is kept apart in shrouding top space. Before the stay cord is straightened, the pressure of the space above the sealing plate is gradually reduced, and in the sterilization process, partial steam is condensed after contacting with food, so that when the air pressure is lower than a preset value, the pneumatic control valve is opened, and the steam chamber supplies steam into the sterilization cylinder.

When the sealing plate stops moving downwards, the bearing plate continues to move downwards until the bearing plate moves downwards to be below the feed port and the discharge port; under the mutual extrusion of the food, the food enters the bearing plate, and then the bearing plate is moved upwards through the lifting mechanism. After the support column on the bearing plate contacts with the shrouding, the bearing plate will promote the shrouding and together shift up, then frustum and taper hole break away from the cooperation, space and shrouding below space intercommunication above the shrouding. In the process that the bearing plate continuously moves upwards, steam above the sealing plate enters the space below the sealing plate through the taper hole. As the bearing plate moves upward, the pressure in the space above the bearing plate will also increase. The heating device heats the steam and detects the temperature through the temperature sensor so as to maintain the high temperature of the steam; thereby subjecting the food to a high temperature, high pressure, sterile environment.

In this scheme, when the bearing plate was in feed inlet and discharge gate top, support column on the bearing plate just breaks away from with the shrouding to can prevent that outside cold air from getting into the space of shrouding top through feed inlet and discharge gate, make the temperature in shrouding top space reduce.

The beneficial effect that this scheme produced is:

when the bearing plate moves downwards, steam between the sealing plate and the bearing plate enters the space above the sealing plate, so that high-temperature steam is prevented from leaking, and the steam can be sterilized and utilized next time; meanwhile, the pressure is reduced without condensing the steam through temperature reduction, so that the utilization rate of the steam heat energy can be improved.

The scheme changes the space size through the movement of the bearing plate, and can quickly carry out pressurization and depressurization; therefore, the food can be quickly brought into a sterilization state, and the pressure can be quickly reduced, so that the food can be quickly taken out.

The first preferred scheme is as follows: as a further optimization of the basic scheme, the upper end of the sterilizing cylinder body is provided with a detachable sealing cover, so that the upper part of the sterilizing cylinder body can be overhauled after the sealing cover is detached.

The preferred scheme II is as follows: as a further optimization of the first preferred embodiment, the bearing plate is provided with a roller shaft, so that the food can slide into and out of the bearing plate conveniently.

The preferable scheme is three: as a further optimization of the second preferred scheme, a cooling water circulation pipeline is arranged at the lower part of the sterilization cylinder body, and the cooling water circulation pipeline is spirally wound outside the sterilization cylinder body. When the bearing plate moves down, food can pass through the cooling water circulation pipeline below the sterilizing cylinder body, so that the food can be cooled, and the food is convenient to carry manually after being discharged from the discharge hole.

The preferable scheme is four: as a further optimization of the third preferred scheme, the lower end of the sterilizing cylinder body is provided with a linkage switch, the linkage switch is electrically connected with the conveying part, and the bearing plate presses down the linkage switch, so that the linkage switch controls the conveying part to operate, the conveying part is more intelligent, and food is prevented from being accumulated at the feed inlet.

The lifting mechanism is connected with the bearing plate 11, the bearing plate 11 can slide up and down in the sterilization barrel 10 through the lifting mechanism, and the lifting mechanism adopts the hydraulic oil cylinder 30. The supporting columns are arranged on the bearing plate 11, the supporting columns can support the sealing plate 12 to enable the sealing plate 12 and the bearing plate 11 to form a food loading space, the lower portion of the sterilizing cylinder body 10 is provided with a feeding hole 17 and a discharging hole 18 which are oppositely arranged, the conveying belt comprises a feeding portion 21 and a discharging portion 22, the feeding portion 21 and the discharging portion 22 both adopt conveying belts, the feeding portion 21 corresponds to the feeding hole 17, and the discharging portion 22 corresponds to the discharging hole 18; in addition, in order to facilitate the food to slide on the bearing plate 11 smoothly, a plurality of roller shafts 112 are provided on the bearing plate 11. The upper end of the sterilizing cylinder 10 is provided with an air inlet, the steam chamber 16 is communicated with the sterilizing cylinder 10 through the air inlet, a pneumatic control valve 161 is arranged in the steam chamber 16, and the opening and closing of the pneumatic control valve 161 are controlled by the pressure in the sterilizing cylinder 10; when the pressure of the sterilizing drum 10 is lower than the preset value, the steam chamber 16 will supplement the steam into the sterilizing drum 10.

In order to facilitate the maintenance of the upper part of the sterilizing cylinder 10, a sealing cover 14 is provided at the upper end of the sterilizing cylinder 10, the sealing cover 14 is hinged at the upper end of the sterilizing cylinder 10, and the sealing cover 14 and the sterilizing cylinder 10 can be fixed by bolts. The lower part of the sterilizing cylinder 10 is provided with a cooling water circulating pipeline 15, the cooling water circulating pipeline 15 is spirally wound outside the sterilizing cylinder 10, and when the bearing plate 11 moves downwards, food can pass through the cooling water circulating pipeline 15 below the sterilizing cylinder 10, so that the food can be cooled.

When the closing plate 12 stops moving downwards, the bearing plate 11 continues moving downwards until the bearing plate 11 moves downwards below the feed inlet 17 and the discharge outlet 18; under the mutual pressing action of the food, the food enters the bearing plate 11, and then the bearing plate 11 is moved upwards by the lifting mechanism. After the support column on the bearing plate 11 contacts with the sealing plate 12, the bearing plate 11 will push the sealing plate 12 to move upward together, so that the frustum 121 is disengaged from the taper hole, and the space above the sealing plate 12 is communicated with the space below the sealing plate 12. During the process of the bearing plate 11 moving upwards continuously, steam above the sealing plate 12 enters the space below the sealing plate 12 through the taper hole. As the bearing plate 11 moves up, the pressure in the space above the bearing plate 11 will increase.
