Abstract

The invention relates to technological processes for the preparation of products in the food industry, for example, for the preparation of sauces and pastes, and makes it possible to increase the productivity and efficiency of the apparatus. The evaporator contains a vertical case on the supports, a cover and a mixing device. The lower and upper shirts are connected using a condensate drain tube, the lower end of which is fixed in the lower part of the lower shirt, and the upper end in the lower part of the upper shirt. The upper jacket is heated by condensate coming from the lower one, with constant control of temperature from the upper jacket and its regulation in it by opening and closing the valve on the condensate drain line from the upper jacket, thereby making more complete use of steam heat to heat the product. 1 hp f-ly, 1 ill.

Description

This invention relates to a process for the preparation of products in the food industry, for example, in the preparation of sauces and pastes.

The aim of the invention is to increase the productivity and efficiency of the apparatus,

The drawing shows a diagram of the evaporator.

The evaporator contains a vertical body 1 with a lid 2. In the lid of the apparatus there is a hatch 3 to exit the evaporating fraction. A mixing device 4 with an electric actuator 5 is installed inside the apparatus. On the lower and upper parts of the apparatus case, respectively, the main 6 and an additional 7 steam jackets are fixed. For removal of condensate from the main jacket 6 to the additional shirt 7, an overflow tube 8 is installed inside the lower shirt. Steam is supplied to the lower shirt of the apparatus through a pipe 9 and

discharged in the form of non-condensed vapors or condensate through the main pipe 10 or additional pipe 11, depending on the position of the three-way valve 12. On the common outlet pipe there is a shut-off valve 13 with a remote-controlled actuator controlled by the temperature regulator 14 depending on the state of the temperature sensor 15 located in the additional jacket. The device contains hatches 16 loading and unloading 17.

The device works as follows.

Through the hatch 16, the product is loaded into the apparatus until the upper end of the additional jacket and the drive 5 of the agitator is switched on. The apparatus is connected to the steam line. Valve 12 is installed in one of two positions. In the position in which the outlet 10 is connected to the outlet, the valve 12 provides for the removal of condensate at a relatively high pressure of the heat transfer medium.

providing a rise in condensate in the top jacket to the top level. At a relatively low vapor pressure, the valve 12 is set to a position in which the outlet 11 is connected to the outlet. The temperature controller 14 is turned on, which is set to the temperature value in the jacket 7 corresponding to the maximum allowed. As a temperature regulator 14, any on-off regulator can be used. In the process of heating in the main lower jacket, steam condenses and flows to the lower part of the shirt, from which it is pushed as condensate through the tube 8 to the upper shirt 7. In case the temperature in the upper shirt is lower than the maximum allowed value, then temperature controller 14 gives a signal to open the valve 13 and condensate through the jacket 7 through the pipe 10 or 11 enters the drain.

Thus, to heat the product, the maximum amount of energy coming from the inlet coolant with the largest heating area is used. In case the temperature in the upper jacket exceeds the set value, the valve 13 is closed and the apparatus continues to heat only by condensation of the vapor in the lower jacket when the upper jacket 7 is filled with condensate. As the temperature in the jacket 7 decreases, the process repeats. Thus, in the apparatus proposed, the product is evaporated with high productivity and economy.
