Description

Auto popping machine}

The present invention relates to an automatic popping machine which automatically heats grains and expands them under high pressure so that a series of processes for manufacturing a snack are performed automatically.

In general, a grain auto-popping machine which automatically heats food such as grains or dried fish and expands it under high pressure to manufacture a snack is automatically performed. The popping drive by cylinder type and electric motor are driven by the driving method. It is divided into a crank mechanism and a popping drive using a cam.

The cylinder system is published in Korean Patent Publication No. 99-79239 "Food automatic popping device",

The actuating means for compressing and popping the material is connected to the support bar while the upper block, the center block, and the lower block, which are mold parts, are sequentially opposed to the support bar, and the center block is fixed to the table by a post. Ascending and descending by the cylinder provided in, the lower block is suspended by a spring on the center block to be operated by one cylinder.

When the upper block is lowered by the operation of the cylinder, the pressure sheet installed in the upper block enters the through hole of the center block to heat pressurize the raw material for a predetermined time, and then the pressure sheet is momentarily raised slightly by the operation of the cylinder to expand the raw material. And while the upper mold is raised by the operation of the cylinder at the same time the upper mold is raised together with the elasticity of the spring is made of a process that allows the popping material to be lifted up to the center block to be discharged to the outside.

However, the upper and lower blocks are essentially equipped with a heater to pop the material to be heated to about 100 degrees or more. The pressure sheet of the upper and lower blocks is coupled up and down to the through hole (chamber) in the center block to compress the material located therebetween. In order to achieve the compression function, the diameter of the pressure sheet and the through-hole should be fitted within 0.05mm.The metal material is changed in diameter due to thermal expansion such as heat caused by heater and surrounding climate. The expansion tolerance is much larger than the diameter of the through hole, and the fitting tolerance is greatly reduced. After popping during use, the pressure sheet is forced into the through hole of the spring, and the elasticity of the spring does not fall out well. There is a case that cannot be supported.

On the other hand, the pop-up driving method using the crank mechanism and the cam as the driving source of the motor was proposed Utility Model Registration No. 188637 automatic icing device.
