Intermediate wave infrared and pulse vacuum drying integrated device of granulate prepared food and using method thereof

Abstract

The invention discloses an intermediate wave infrared and pulse vacuum draying integrated device of granulate prepared food and a using method thereof, belonging to the field of food dehydration and drying machinery. The intermediate wave infrared and pulse vacuum draying integrated device consists of a feed valve, a baffle valve, an intermediate wave infrared heating cavity, intermediate wave infrared transmitting tubes, drying tubes, a gas distributor, a drying tube plug, a gas flow adjuster, a gas-solid separator, an unloader, a cooler, a refrigerator, a vacuum storer, a vacuum pump and a control panel, wherein a material enters the drying tubes through the feed valve and the baffle valve; the baffle valve is machined to be a hole plate to prevent particle loss during drying; the drying tubes are material drying and flowing channels; the intermediate wave infrared heating cavity is a cylindrical vacuum container; the intermediate wave infrared transmitting tubes are uniformly distributed in the cavity; the drying tubes are uniformly arranged between the intermediate wave infrared transmitting tubes. By the device, the material can spray and rotate under the condition of intermediate wave infrared vacuum draying, so that the purpose of high-efficiency and uniform drying is reached, the drying period is shortened by over 40%, and the production cost is reduced.

Description

technical field [0001] The invention relates to an integrated device for uniform drying of medium-short-wave infrared and pulse vacuum for granular prepared food and a method for using it, which is suitable for medium-short-wave infrared vacuum uniform pulse spray drying of granular materials in the food industry, and belongs to the field of food dehydration processing and drying machinery equipment. Background technique [0002] At present, infrared (electromagnetic wave with a wavelength between 0.72 and 1000 μm) technology has been gradually applied in military and civilian research fields such as aerospace, aviation, remote sensing, industrial inspection, food, medicine, chemical industry, and petroleum industry. For infrared spectroscopy, there are different divisions in different fields. Generally speaking, infrared technology can be divided into four categories: near infrared, mid-infrared, far-infrared and high-infrared according to wavelength. Research on near-infra...

AI Technical Summary

Problems solved by technology

In the 1950s, Curcio and Petty used near-infrared transmission spectroscopy to conduct research on moisture detection, but most of the undamaged and undamaged materials of food and agricultural products are "opaque" to near-infrared, and it is difficult to measure their transmittance.

At present, there are three outstanding problems and demands in the vacuum drying of agricultural products in my country: (1) The vacuum drying of agricultural products has problems such as large energy consumption, long drying time, and high cost, and there is a strong demand for efficient vacuum drying technology

(2) Short-wave infrared vacuum drying of agricultural products has problems such as weak penetration, poor drying uniformity, low yield, and aggravated product quality deterioration. There is a strong demand for efficient and uniform drying technology

The patent produces uneven drying of materials
