Description

The invention relates to the equipment of the canning and food concentrate industry, namely to combined devices, and can be used in the production of puree concentrates from fruits and vegetables.

Known machine 1P31, designed to rub the pulp of cherries, plums, apricots and peaches with the separation of seeds from the pulp (Machines and equipment for food production. In 2 books: Textbook for universities. / S.T. Antipov, I.T. Kretov, A.N. Ostrikov et al .; Edited by the academician of the Russian Academy of Agricultural Sciences V.A. Panfilov. - M.: Higher school, 2001. T. 1, p. 382), which contains a housing, a bed, a loop shaft, loading hopper, mesh fixed in the housing, a waste exit tray and a collection of rubbed mass.

The closest in its technical essence and the achieved effect is a closed digester (Flamenbaum, B.L. Technology for preserving fruits, vegetables, meat and fish. / B.L. Flamenbaum, A.A. Brovchenko, A.F. Zagibalov and other / Edited by B.L. Flamenbaum. - 2nd ed., revised and enlarged. - M .: Kolos, 1993. - 320 p.), containing a loading hopper, a cylindrical-conical housing, inside of which there is a vertical hollow shaft with auger and paddle mixer. The conical part of the body is equipped with an external steam chamber, and an unloading valve is installed in the lower part of the conical body.

The disadvantages of the known devices are:

- insufficient balance of the chemical composition of the obtained puree concentrate due to the impossibility of processing several types of products;

- significant material and energy costs due to the need for transshipment and transport operations between machines installed in the line;

- low productivity due to the time spent on auxiliary operations.

An object of the invention is to develop an apparatus for the production of puree concentrates, which allows to improve the quality of the finished puree through the consistent use of combined mechanisms for wiping, boiling, stirring, introducing the necessary additional components (sugar syrup, flavorings, structurants, stabilizers, etc.) and achieve more uniform heat treatment of fruits, reduction of material and energy resources due to the need for transshipment and transport operations between machines installed in the line.

The task is achieved in that a device for the production of puree concentrates from fruits or vegetables is developed, the new one is that it contains a washing machine and a vertical case with a steam jacket, with a vertical shaft with a stirrer located in it, a heat chamber and vacuum are sequentially located under the washing machine -camera, the cylinder-conical part of the heat chamber is equipped with a steam chamber with nozzles for supplying steam and condensate drainage, a vertical shaft with blades is installed inside the heat chamber, the slope of which is adjustable, in its cylindrical part there is a nozzle for supplying various food additives, and in its lower conical part there is a nozzle that communicates with a vacuum chamber, in the lateral cylindrical part of which there is a nozzle for removing vaporized vapor, and in the lower part unloading auger.

The drawing shows a General view of the apparatus for the production of puree concentrates.

The apparatus for the production of puree concentrates from fruits or vegetables (see drawing) includes a wiper machine 1, under which a heat chamber 2 and a vacuum chamber 3 are arranged in series.

The washing machine consists of a loading hopper 9, a housing 6, inside which a cylindrical screen drum 7 is located, and a horizontal shaft 8.

Case 6 of the machine is two sidewalls mounted on a bed and covered with an easily removable shell. On two bearings 10, the shaft 8 rotates with the feeding screw 4 and pests 5. The rubbed mass passes through the sieve drum 7 and enters the heat chamber 2. The peel, seeds or seeds (waste) are removed from the washing machine through the output tray 11.

The heat chamber 2 is a cylinder-conical housing 16, which is externally provided with a steam jacket 12 and nozzles for supplying steam 13 and condensate 14. A vertical shaft 15 is installed inside the heat chamber 2 with blades 17 that are capable of adjusting the angle of inclination. In the cylindrical part of the heat chamber 2 there is a pipe 18 for supplying various food additives, and in its lower conical part there is a screw coil 22 for forced transportation of the product and a nozzle 19.

The vacuum chamber 3 communicates with the heat chamber 2 through the nozzle 19. In the upper part of the vacuum chamber 3 there is a nozzle 20 for connection with a vacuum pump to maintain vacuum and ensure the removal of water vapor generated by finely dispersed pulverized pulp at the exit of the nozzle 19. In the lower parts of the vacuum chamber 3, a discharge screw 21 is installed for the finished product.

The proposed combined apparatus for the production of puree concentrates works as follows.

In the receiving funnel of the loading hopper 9 of the washing machine 1, the initial product, i.e. fruits and vegetables washed and peeled and stalked. The drive of the washing machine 1 is turned on, driving the screw 4. The initial product through the loading hopper 9 enters the housing 6 of the washing machine 1. The processed product by the screw 4 is moved along the axis of the cylindrical screen drum 7 to the pests 5. Under the action of the rapidly rotating pests 5, the doughy mass is captured by pests , is driven into rotational motion and under the action of centrifugal force and pressure of the pests, the flesh is pressed through a cylindrical screen drum 7 and enters the heat chamber 2.

The peel, seeds or seeds (waste) are advanced to the output tray 11 and are removed from the washing machine 1 through it.

Then, steam is supplied through the pipe 13 to the steam jacket 12 of the heat chamber 2, which heats the inner surface of the conical part of the heat chamber 2, condenses and is removed through the pipe 14.

At the same time, an adjustable drive (not shown) is turned on and the vertical shaft 15 with blades 17 installed inside the heat chamber 2 starts to rotate. The frequency of rotation of the shaft 15 is regulated by the drive. The angle of inclination of the blades 17 required for each type of product is set in advance. In this case, the puree mass is captured by the rotating shaft 15 with the blades 17 and pressed against the inner surface of the conical part of the heat chamber 2.

In the heat chamber 2, the crushed and heated particles of the fruit are captured by the blades 17 and are rotationally driven. Due to the angle of inclination of the blades 17 and the centrifugal force, the puree mass is distributed evenly over the inner surface of the conical part of the heat chamber 2. Due to the conductive heat exchange with the inner surface of the heat chamber 2, the treated mass is heated to the required temperature.

Then, through the pipe 18 located in the cylindrical part of the heat chamber 2, a mixture of various food additives (sugar syrup, flavorings, structure-forming agents, etc.) is fed, which not only increase the nutritional value of the crushed fruit particles, but also contribute to significant changes in their structure, preparing them for subsequent processing in a vacuum chamber 3.

Pre-heated particles of the fruit by a screw coil 22 are pumped into the nozzle 19.

Next, the drive of the vacuum pump (not shown) is turned on and air evacuation starts from the vacuum chamber 3 and then maintains a predetermined vacuum value. The drive of the unloading auger 21 mounted in the lower part of the vacuum chamber 3 is also included.

After injection of the compressed mashed mass by a screw coil 22 into the nozzle 19, finely dispersed atomization of the mashed mass occurs at the entrance to the vacuum chamber 3.

As a result of a sharp decrease in pressure (since vacuum is maintained in the vacuum chamber), instantaneous evaporation of moisture from the product occurs. The water vapor generated by evaporation from the pulp mass is removed through a pipe 20, which is connected to a vacuum pump to maintain a vacuum.

Unloading auger 21 concentrated mashed mass is removed from the vacuum chamber 3 and sent for further packaging.

Thus, the use of the proposed apparatus for the production of puree concentrates from fruits or vegetables allows you to:

- receive puree concentrates of a given composition with the introduction of the necessary additional components (sugar syrup, flavorings, structure-forming agents, stabilizers, etc.) for their further use in various sectors of the food industry;

- to reduce the specific energy consumption for the production of puree concentrates due to the consistent use of combined mechanisms for wiping, boiling, mixing, introducing the necessary additional components and more uniform heat treatment due to the use of rational designs of the heat chamber and vacuum chamber;

- reduce material costs due to the elimination of auxiliary and reloading operations and increase the productivity of the apparatus due to the transition to a continuous mode of operation.
