Description
Technical Field
The invention relates to the technical field of grain processing machinery, in particular to a grain surface high-temperature sterilization device.
Background
The stored grain loss caused by insect and mildew pollution in China is up to more than 200 million jin each year, and according to statistics, the annual average loss rate of the grains in China is more than 5 percent due to mildew, germination and other problems. The food with mildew produces aflatoxin, which is the most deadly biological carcinogen found at present, and canceration can be caused undoubtedly when a human body intakes the food with mildew for a long time. In order to control excessive propagation of mold during grain storage, a drying method is commonly used by storage enterprises to reduce water activity to control growth of microorganisms and a method of fumigating by using chemicals, but generally, low hot air temperature drying is adopted commercially to ensure rice milling quality, the temperature is low enough not to inactivate the mold, the mold is only forced to be in a dormant state, secondary pollution is caused by growth once the temperature and the humidity reach proper conditions, and the chemical method has the defects of chemical reagent residue and the like, and is not suitable for the requirement of green ecological grain storage development. The need for developing new alternative technologies is becoming more stringent.
Disclosure of Invention
The invention provides a high-temperature grain surface sterilization device, which aims to solve the problems of poor sterilization effect and grain pollution in the prior art.
The technical scheme adopted by the device for solving the technical problem is as follows:
the utility model provides a grain surface pasteurization device, which comprises a frame, a retort, the heat supply ware, hot-blast generator and draught fan, retort import sets up the feeding funnel, feeding funnel side-mounting material motor, the built-in auger of retort, auger motor drive auger rotates, the heat supply ware links to each other with hot-blast generator, hot-blast generator export links to each other with the draught fan, the draught fan export links to each other with the dashpot, the air-supply line that the dashpot top was through a plurality of parallel connection links to each other with retort bottom, retort top links to each other with hot-blast generator through a plurality of parallel connection's play tuber pipe.
The joint of the air inlet pipe and the bottom of the sterilizing cylinder is provided with a filter screen.
The joint of the air outlet pipe and the top of the sterilizing cylinder is provided with a filter screen.
The sterilizing cylinder is obliquely arranged, and the inlet end is higher than the outlet end.
The working principle of the invention is as follows: the heat supplier can adopt heat supply equipment such as an electric heater or a heat conducting oil furnace and the like, the heat supplier sends a heat source into a hot air generator to generate hot air with the temperature of 180-200 ℃, the hot air is sent into a buffer tank through a draught fan and then enters a sterilizing cylinder through an air inlet pipe connected in parallel, the hot air after heat exchange returns to the hot air generator through an air return pipe through an air outlet pipe connected in parallel, meanwhile, grain crops enter the sterilizing cylinder through a feeding hopper under the stirring of a feeding motor, the packing auger motor drives the packing auger to rotate so as to continuously stir and push the grain crops from an inlet to an outlet, and the grain crops are contacted with the sent high-temperature hot air for a short time in the moving process, so that the bacteria on the surface of the grain are killed by utilizing the high temperature, and finally the grain crops are sent out from the outlet of the sterilizing cylinder.
The invention utilizes high-temperature hot air to instantly contact and kill the grain surface, has obvious sterilization effect, controls the growth and the propagation of the mold on the grain surface, has the total amount of the mold lower than 2log cfu/g and the water content of the grain reduced by about 0.5 percent through detection, can effectively prolong the quality guarantee period of the grain, has short sterilization flow and simple and easy technical process, does not need to add chemical bactericide, avoids the secondary pollution of the grain in the processing process, reduces the environmental pollution, and also furthest reduces the influence on the internal quality of the grain.
