Infrared on-line control type stir-frying machine

Abstract

The invention provides an infrared on-line control type stir-frying machine and relates to a device used for stir-frying materials, which is especially suitable for stir-frying traditional Chinese medicine materials, agricultural products, foods and the like. In the invention, at least two infrared temperature measurement instruments are adopted to measure the temperature of materials stir-fried by the stir-frying machine, wherein one infrared temperature measurement instrument measures the temperature of the drum wall of a stir-frying drum which contacts with a heat source and is arranged at one side of the stir-frying machine, the other infrared temperature measurement instrument measures the temperature of the materials in the stir-frying drum of the stir-frying machine, and the rotation speed, the feeding and the discharge of the heat source and the stir-frying drum of the stir-frying machine are controlled according to the measured temperature of the drum wall and the measured temperature of the materials. The invention integrates an on-line infrared temperature measurement technology and the stir-frying machine, improves the defect of the traditional contact type temperature measurement of the existing stir-frying machine, has a positive meaning in the aspect of the accurate on-line temperature measurement and control of the stir-frying machine, meets the actual demand of large-scale stir-frying and has wide application and favorable popularization value.

Description

Technical field: [0001] The invention relates to an infrared on-line control type frying machine device, which is especially suitable for frying traditional Chinese medicines. Background technique: [0002] Traditional Chinese medicine processing is a set of processing and manufacturing techniques implemented on Chinese medicinal materials, which is the concentrated expression and core of traditional Chinese medicine skills. And frying is an important link in the processing of Chinese herbal medicines and the weakest link in important production. At present, about 30% of Chinese herbal medicines need to go through this frying procedure in China. [0003] The process of frying traditional Chinese medicine can be regarded as a binary processing thermal system composed of a heat source and a heated body. Wherein: the heating body also includes loading containers, medicines (including medicinal materials and processing auxiliary materials), etc. The heat source transfers heat ...

AI Technical Summary

Problems solved by technology

First of all, the inner wall of the frying cylinder is affected by the friction, scaling or cleaning of medicinal materials for a long time, which changes the surface roughness and refractive index of the cylinder wall. This is a taboo for infrared temperature measurement, and the temperature of the cylinder cannot be accurately measured.

Secondly, during the frying process, the heat energy is transferred to the drug through the frying tube, but the size of the heat source needs to be controlled according to the temperature or color of the material to be fried, and the thermal resistance effect of the frying tube between the heat source and the material makes It is difficult to achieve the temperature that meets the actual needs of the material by controlling the heat source
