Vacuum freeze-drying food product installation

Abstract

The invention relates to the field of drying materials, in particular to vacuum drying devices, and can be used for drying food products, such as liquid fermented milk products, vegetables, mushrooms, fruits, herbs, etc. The objective of the invention is to expand the technological and functional capabilities of a vacuum chamber, improving the quality of drying and operational characteristics, preserving the quality and beneficial properties of food products. The technical result of the claimed invention is to ensure uniform cooling and heating of food products in a vacuum environment, without the impact of heat treatment, which allows preserving the beneficial properties of the food product, regardless of the type and size of the food product being dried. The technical result is achieved by a vacuum freeze-drying installation for food products, comprising a first housing with a vacuum chamber located in its upper half with plates inside it, doors located in the upper part of the first housing, a condenser located in the first housing under the vacuum chamber with the ability to control the vacuum drying process due to the cover, a second housing containing a heat exchanger and a circulation pump in the upper part of the housing, Receivers connected to a vacuum pump are located at the bottom of the heat exchanger, while compressors are located at the bottom of the second housing. An electronic control system is installed at the end of the second housing. According to the invention, the plates are designed as a removable section of plates rigidly attached to the distribution channel for the transport agent, and on both sides of the elongated side portions, the plates are attached to metal strips. In this case, the plates are designed with the possibility of heating and cooling the transport agent, and the distance between the plates in the plate section is from 20 to 150 mm, and the section of plates is designed with the possibility of fastening and detaching it to / from the housing, containing at least two oil channels for pumping the transport agent into the plates and removing it from them.
