Continuous parching equipment

Abstract

The invention relates to continuous parching equipment which comprises a rack, a feeding mechanism, a parching mechanism, a discharging mechanism and an oil stain separation and collection device. The parching mechanism is mounted above the rack, the feeding mechanism and the discharging mechanism are arranged at the feeding end and the discharging end of the parching mechanism respectively and communicated with the parching mechanism, and the parching mechanism comprises a roller and a heating element. The roller comprises an inner barrel and an outer barrel arranged outside the inner barrel in a sleeving mode, a closed air channel is formed between the inner barrel and the outer barrel, and the heating element is arranged in the air channel. An air inlet of the oil stain separation and collection device is communicated with the interior of the roller, an air outlet of the oil stain separation and collection device is communicated with the air channel, and high-temperature smoke generated in the roller is purified through the oil stain separation and collection device and then is subjected to secondary heating through the air channel to be guided back to the roller. In the seed parching process, cyclic utilization of heat is achieved, it is guaranteed that the equipment is free of emissions, the production environment can be clean, and the aims of saving energy and reducing emissions are achieved.

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to a continuous roasting and frying equipment, which can be used for stir-frying various oil-pressed foods, such as rapeseed, sesame, peanut, melon seeds and the like. Background technique [0002] Recently, most of the existing drying and roasting equipment adopts the drum type, and the drying and roasting of seeds is realized by manually burning coal or other fuels. The quality of the drying and roasting seeds depends on manual inspection, and the stability of product quality control is poor. , Inconsistent, at the same time, due to the burning of fuel to produce open flames, which brings hidden dangers to fire safety, and fuel heating is labor-intensive, high labor costs, difficult to control the temperature, affecting the quality of rapeseed, burning fuel produces a lot of smoke, polluting the production environment.

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned technical scheme has changed the traditional way of burning fuel for heating, and controls the uniformity of the frying temperature through thermal circulation and convection, there are still some deficiencies in the actual use process: although the technical scheme is improved by adding a front fan and a rear fan Improve the heating uniformity of the roasting mechanism and shorten the roasting time, but the roasting mechanism adopts an open side, which will generate a lot of oily fume during the process of drying the fried seeds. On the one hand, it will pollute the production environment of the workshop, on the other hand, the oily fume It will adhere to the front fan and the rear fan, and part of it will blow into the fried food during work, which will affect the quality of the fried food

In addition, since the oil fume generated during the drying and frying process has a certain calorific value, the direct discharge will result in a great waste of heat, which cannot achieve the purpose of energy saving and emission reduction
