Energy-saving consumption-reduction system of vacuum freeze-drying machine

Abstract

The invention provides an energy-saving consumption-reduction system of a vacuum freeze-drying machine, and belongs to the field of vacuum freeze-drying equipment. The energy-saving consumption-reduction system of the vacuum freeze-drying machine structurally comprises an ice catching tank and a drying tank which are communicated mutually, wherein the ice catching tank is internally provided with an evaporator; the evaporator is sequentially connected with a refrigerating compressor outside the ice catching tank, an evaporative-type condenser and a throttling device according to the circulating flowing direction of a refrigerant; the ice catching tank is connected with a vacuum system; the bottom of the ice catching tank is provided with an ice water return pipe connected with an ice water energy storage groove; the drying tank is internally provided with two or more than two heating plates horizontally at intervals; the heating plates are internally provided with heating medium circulating pipes; the heating medium circulating pipes are connected with the heating medium circulating pumps and a heating medium heat exchanger outside the drying tank; and the heating medium heat exchanger is also connected with a heating evaporation pipeline. Compared with the prior art, the energy-saving consumption-reduction system of the vacuum freeze-drying machine has the characteristics of reasonable design, energy conservation and consumption reduction, cost consumption reduction, yield improvement and the like.

Description

technical field [0001] The invention relates to a vacuum freeze-drying device, in particular to an energy-saving and consumption-reducing system for a vacuum freeze-dryer. Background technique [0002] Vacuum freeze drying, English "Freeze Dried" referred to as "FD". This technology originated in the early 20th century. Using the principle of sublimation of ice, the material containing moisture is frozen and placed in a high-vacuum drying tank to provide a certain latent heat of vaporization to sublimate the moisture in the material to achieve the purpose of dehydration and drying. . At present, vacuum freeze-drying equipment has been widely used in food, agricultural and sideline products deep processing and other fields, and plays an increasingly important role in improving food quality and developing agricultural industrialization. [0003] The application of vacuum freeze-drying equipment in the processing of food and agricultural by-products, its finished products can...

AI Technical Summary

Problems solved by technology

However, vacuum freeze-drying equipment has been plagued by the rapid development of FD products due to complex equipment, large investment, long drying time, high manufacturing cost, and high energy consumption in operation.

Especially in recent years, due to the impact of the international financial crisis and the sharp increase of various costs in China, FD companies have entered the era of meager profits. If this continues, it will inevitably lead to the collapse of FD companies

For decades, FD products have been crowned with the title of "cosmic food". None of the energy of the machine is recycled and reused, resulting in high power consumption, high water consumption, and high cost
