Description

The invention relates to devices that are used in the food industry and catering.

A device is known for trimming the ends of vegetables, preferably eggplants, comprising a transporting mechanism with a fruit gripper and a cutting knife.

A disadvantage of this device is the impossibility of performing an operation to remove peel from the fruit.

A device is known for peeling fruits, especially eggplants, comprising a drive table, a conveyor mechanism, a cutting knife, heating elements located above the table, and a drive.

A disadvantage of the device is the low degree of mechanization and intensification of the process, and the low quality of fruit cleaning.

The aim of the invention is to intensify and mechanize the process and improve the quality of fruit cleaning.

Figure 1 a, b shows a schematic diagram of a device, side view and top; on the

figure 2 is a section of the tear-off rollers of the device; in Fig.Z is the profile of the table.

The device comprises a device for spontaneous feeding of fruits with orienting screw descent 1 and funnel 2. The transporting mechanism of the carousel type 3 has perforated sections 4 for piece feeding of fruits located in a circular line. On both sides of the sections in a certain sector of the device there are fixed semi-ring heaters (heating elements) 5. Under the transporting mechanism, a fixed table 6 is mounted, which has a cutting knife 7, as well as a device 8 for feeding fruits into the grip of the tear-off rollers 9, 10. The device 8 consists of recesses in the table and spring-loaded springboard. The tear-off rollers 9, 10 (Fig. 2) are made of the same diameter and have half-ring grooves, which ensure fruit grasping and peeling by changing their profile. The third roller 11 has a protrusion in the form of a groove, which is in contact with the drive roller 9. The rollers 9.10, as well as the rollers 9.11 have a clip VI VI VI VI VI

other devices 12, providing contact of the rollers in case of capture of fruits of a larger diameter and the mechanism to change the distance between the axes of rotation of the rollers. To collect peeled fruits, the device is equipped with drives 15, 16, providing synchronous operation of the transporting mechanisms and tear-off rollers

The device operates as follows.

Sort eggplant sorting and washing piece by piece stacked on a spiral descent 1 stalk to its center. As the descent 1 is filled, the fruits, under the influence of their own weight, are fed into the funnel 2, from which they enter the sections 4 of the transporting mechanism 3, which rotates intermittently. The included heating elements 5 automatically maintain the required air temperature in the heat treatment zone of the fruit. The fruits are subjected to heat treatment as they move, then the unheated zone of the device passes, where the temperature and moisture in the surface layers are equalized for a certain time.

Further, the fruits, sliding along the stationary table (Fig. 3), pass the zone of the cutting knife 7, are cut, falling into the recess of the stationary table and then onto the spring-loaded springboard, the fruits are individually delivered to the gripper rollers 9, 10 (in this case, the size differences of the fruits are leveled by the spring force , providing a tight grip of all fruits).

At the time of the transporting mechanism, the working cycle (rotation through 360 °) of the tear-off rollers 9, 10, 11 occurs. As they rotate, the opening of the gap formed by the grooves decreases (due to a change in the profile of the grooves). The friction forces of the surface of the grooves on the peel of the fruit after their heat treatment become greater than the adhesion forces of the peel to the adjacent cat. To provide a larger contact area between the rollers and the skin (which proportionally increases the adhesion force between them), semicircular grooves are provided on the rollers. Reducing the size of the hole (cylindrical gap) formed by the grooves allows the fetus captured by the rollers at a certain moment not to enter further,

and squeezed out of the gap (more precisely, it is squeezed out, because the adhesion of the peel to the groove surface is currently stronger than the adhesion of the peel to the cat

fetus). After peeling the fruit, the peel with the peduncle falls into the zone of action of the rollers 9.11, and the fruit of the fruit is returned to the corresponding section of the mechanism, and in the next cycle of its operation, under the influence of its own seqa, it is removed into the container 14. To unload the peeled fruits, the stationary table has a through hole. To remove the peel with the stalk in the hopper 13, the device comprises a pair of rollers 9, 11.

In this case, the roller 11 has a special protrusion imitating the profile of the groove of the roller 9 in shape, which ensures the capture density of the peeled skin. To ensure the reliability of the rollers 9, 10, 11 in case of varying size and shape of the fruit, the drive roller 9 is connected by a pressing device 12 with rollers 10, 11, allowing these rollers to work with a change in the distance between their axes

rotation.

The device allows you to carry out on it all the technological operations for cleaning eggplant, intensify and mechanize the process, improve quality

peeling fruit.
