High-efficiency and energy-saving gas compression string stacked type temperature raising, refrigerating, dehumidifying and drying device

Abstract

The invention discloses an efficient and energy-saving gas compression superposed rapid heating and cooling dehumidification drying device, which can be used for drying treatment of foods and drugs and belongs to the technical field of new application of gas compression devices. The device comprises a plurality of superposed gas compression heating and expansion cooling units, wherein, each gas compression heating and cooling unit consists of an air compressor, a high-pressure heater, a low-pressure cooler, a tubule and a throttle valve; the air outlet pipe of the air compressor is connected with the high-pressure heater; the air inlet pipe is connected with the low-pressure cooler; the high-pressure heater and the low-pressure cooler are connected by the tubule and the throttle valve; the high-pressure heater and the low-pressure cooler are both arranged in an air channel. The invention changes the low-efficiency heating method, i.e., heating cord, of the prior drying devices, transforms electric energy into mechanical energy, releases substantial heat after rapid air compression, achieves air heating drying, absorbs heat and removes moisture through rapid air compression, therefore, the drying efficiency is higher. The gas compression heating and expansion cooling units are superposed and arranged in series to achieve optimum drying temperature and high energy-saving efficiency.

Description

technical field [0001] The invention relates to a new application structure of gas compression equipment, specifically a high-efficiency, energy-saving gas compression cascade type rapid heating and refrigeration dehumidification drying device that can be used in drying treatment of food and medicine. Background technique [0002] With the continuous development of social progress and science and technology, people's living standards are also improving day by day. Therefore, under the existing social environment, people have requirements for food sanitation, processing pollution, convenience, diversification, and not destroying its active ingredients and not losing original flavor or even fragrance. For this reason, the concentration and drying equipment for food and pharmaceutical processing also needs to be updated. [0003] Retrieval of relevant materials including Chinese patents shows that there is no report on a related device that directly utilizes the work of a gas ...
