Problems solved by technology

In order to reduce the increased crushing of the rice milling process, there have been rice mills connected to the blower fan, or strong pulling (strong suction) wind rice mills. One end of the shaft hole is positive pressure air supply, and the forced air rice machine sucks air through the two ends of the main shaft shaft hole). Negative pressure suction at the end, the air intake resistance along the process is large, the air intake volume of each section of the whitening room varies greatly, the suction resistance of the rice mill is large, and the air volume passing through the main milling section (middle section) of the whitening room is small, and it is difficult to suppress the rice milling process. Broken rice produced by increasing the temperature of rice grains

Abstract

The invention discloses an air inlet rice mill with double air sources, which comprises a framework. A rice milling chamber mechanism is arranged in the framework, the lower side of the rice milling chamber mechanism in the framework is connected with a bran suction hopper, the framework at the tail end of the rice milling chamber mechanism is connected with a rice milling discharging mechanism, the rice milling chamber mechanism comprises a spindle, a rice milling roller, a rice sieve component, a feeding hopper and a conveying mechanism, the spindle is connected with the rice milling roller, the rice sieve component and the feeding hopper are arranged in the framework, the spindle in the framework is connected with the conveying mechanism and a transmission and is a hollow structure, a partition board is disposed in a hollow cavity of the spindle, an air spraying hole is arranged on a spindle wall at one end of the partition board, a spindle section with the air spraying hole is connected and communicated with an air spraying fan, an air suction hole is arranged on a spindle wall at the other end of the partition board, a spindle section with the air suction hole is communicatedwith the atmosphere, and an air spraying section and an air suction section are formed on the spindle. The air inlet rice mill is compact in structure and fine in stability.

Description

technical field [0001] The invention belongs to equipment for grinding and peeling grains, in particular to a rice mill. Background technique [0002] During rice processing and milling, rollers grind the surface of rice grains to remove the bran layer. The friction and collision of rice grains in the whitening room will generate a lot of heat, which will increase the surface temperature of rice grains. Due to the poor thermal conductivity of rice grains, the heat is transferred from the surface of rice grains to the surface of rice grains. The internal transmission is slow, so that the rice grains form a large temperature gradient (ie, temperature difference), and the large temperature difference causes thermal stress inside the rice grains. The thermal stress exceeds the inherent strength of the rice grains, which will cause the rice grains to break or burst. In order to reduce the increased crushing of the rice milling process, there have been rice mills connected to the ...
