Abstract

The invention discloses a grain bulking machine which comprises an engine base, wherein a barrel is connected to the engine base; a feeding pipe is upwards communicated to the feeding end of the barrel; an electric motor is arranged at the front side of the engine base and is connected with a small belt pulley; a large belt pulley is connected to the small belt pulley through a driving belt; a pressing bolt assembly is arranged in an inner cavity of the barrel; a discharge opening is connected to the rear end of the barrel; a discharging tail box is connected to the discharge opening; a hydraulic cylinder is arranged on the discharging tail box; an expansion control head in a shape like a frustum with a small front part and a large rear part is arranged at the front end of a piston rod of the hydraulic cylinder; the pressing bolt and a spindle are coaxially arranged and are connected together through a connecting bolt; the large belt pulley is in key connection with the spindle; a cooling heat exchange box is arranged at the front end of the engine base; a front spiral seal and a rear spiral seal are correspondingly arranged on the spindle of the front and rear end parts of a bearing chamber. The grain bulking machine disclosed by the invention has the advantages of good sealing property, uniformity in material stirring, and stability and reliability in work; the thickness of the materials can be controlled, and the cooling of lubricating oil can be kept excellent.

Description

technical field [0001] The invention relates to a grain processing device, in particular to a grain puffing machine for puffing grain. Background technique [0002] The technology of expanding grain has been widely used in recent years, not only for puffed food eaten by people, but also widely used in the field of feed processing technology. [0003] The puffing technology is to put the grain in an extruder, heat and pressurize the grain, so that the water in the grain becomes overheated, and the grain itself becomes soft; when a certain high pressure is reached and the grain is sent out from the puffing container, the high pressure It quickly becomes normal pressure, and at this time, the superheated water in the grain is instantly vaporized and a strong explosion occurs, and the water molecules can expand about 2000 times. The huge expansion pressure not only destroys the external shape of the grain, but also breaks the internal molecular structure of the grain, and cuts ...
