Waste heat recycling equipment used in grain and oil squeezing process

Abstract

The invention discloses waste heat recycling equipment used in the grain and oil squeezing process. The waste heat recycling equipment comprises a grain and oil squeezing tank. An exhaust fan is welded to the top of the grain and oil squeezing tank. The bottom input end of the exhaust fan communicates with the top input end of the grain and oil squeezing tank. The output end of one side of the exhaust fan is fixedly connected with the input end of an exhaust pipe. Through starting of a circulation pump, cold water is guided into a spiral water pipe, cold water and hot water heat energy exchange is conducted, and the output end of the spiral water pipe can be connected into a domestic water pipeline. An air pump is used for guiding outside air into the spiral air pipe for heat energy exchange, the output end of the spiral air pipe guides the cold air into the bottom of the grain and oil squeezing tank, raw materials at the bottom of the grain and oil squeezing tank can be conveniently preheated, smoke can be thoroughly treated, and the dust removal efficiency is improved. Meanwhile, a smoke distribution chamber and a first smoke treatment chamber are in communication through a plurality of ventilation pipelines, and smoke treatment is more uniform.

Description

technical field [0001] The invention belongs to the technical field of waste heat recovery, and in particular relates to waste heat recovery equipment in the grain and oil pressing process. Background technique [0002] The traditional manual oil press is composed of a double stove, a milling plate, a huge trough wood and a suspended oil hammer. Oil mills are generally built on the banks of streams with concentrated villages, abundant water sources and shaded by green trees. Generally, oil extraction starts at the end of April in the lunar calendar every year. Taking mustard oil as an example, the traditional oil extraction process can be roughly divided into seven steps: [0003] First, fry dry. Put the raw and wet rapeseed into the large pot of the stove and fry it dry. The standard of frying is fragrant but not burnt. Pay attention to controlling the heat of the stove, which is related to whether you can squeeze out fragrant and pure oil. Manipulated by a master. [...

Problems solved by technology

[0010] Although the impurities in the oil are also part of the grain during oil extraction, they can also be eaten without filtering, but the oil without filtering has poor quality and poor appearance
