Description

Separate type iron sand roller combined type jet-air rice polisher

The utility model belongs to the Cereals Processing Machines class, particularly a kind of rice mill.

Rice is processed in the paddy husking pearling must uses rice mill.Present widely used jet-air rice polisher mainly is made up of cabinet, cover, main shaft, roller, rice cutter, rice huller screen and spray wind system.The roller leading portion has propelling spiral bar (spiral propeller), and back segment has the shelling white gluten.After paddy enters cabinet from feed hopper, axially be sent on the shelling white gluten by spiral propeller.Paddy in the shelling whitening chamber that the roller and the cabinet inner chamber of band shelling white gluten forms, under the acting in conjunction of shelling white gluten, rice cutter and rice huller screen through rolling, comprehensive function such as extruding, collision, friction and be processed to rice.In process, also utilize the lingering remnants of past customs of dust arrester to spray into main shaft, roller, enter the shelling whitening chamber, to improve processing conditions.That this rice mill has is simple in structure, processing performance good, and is sturdy and durable, and part is easily joined, and is cheap, advantage such as uses, operation, maintenance all make things convenient for.But because its insufficiency, thereby the rice that processes is fair and clear inadequately, and the rice temperature is higher, the broken rice rate height, and power consumption is big, promptly can turn to be yellow in a short time because rice is coarse simultaneously, is difficult for storing.

The purpose of this utility model is developed exactly and a kind ofly can be improved rice quality effectively, satisfies the novel rice mill of people to the more and more higher demand of rice quality requirement.

The purpose of this utility model realizes by following technical proposals: increase by one polishing process after shelling pearling operation; Propeller adopts the high special construction of the reasonable muscle of coarse pitch; The shape that changes semicolumn dignity rice huller screen also cooperates the governor motion of rice cutter to improve machining state.Concrete scheme is: the total roller that is connected with main shaft is made up of the spiral propeller of front end, the cast iron roller of centre and the sand roller roller binding of rear end, thereby makes the processing of rice increase polishing process one.Spiral propeller is that double end advances muscle uniform, has 2～6 shelling white glutens uniform on the cast iron roller, has 2～4 grooves that roll uniform on the sand roller roller, makes total roller obtain optimum structure.Front end one side of the shelling white gluten on the cast iron roller has spray wind elongated slot, also has spray wind elongated slot on the sand roller roller.Change half Cylinder face rice huller screen and be half positive hexagon prism dignity rice huller screen,, reduce the damage of rice to improve the grain of rice condition of rolling automatically.Paddy directly enters sand roller roller and polishes after process shelling pearling.Because the groove that rolls on the sand roller roller is milder, therefore polishing is more even, and the grain of rice is complete, and it is few to crack rice, and brightness increases.The rice huller screen of half positive hexagon prism dignity can make the grain of rice be kept perfectly, and temperature rise is low.Spray to shelling whitening chamber and polishing room from the high pressure draught of hollow shaft and the ejection of spray wind elongated slot, make chaff skin soft surface, can control temperature rise, can purify the chaff powder on grain of rice surface again, make the last class of the rice quality that processes.

The utility model separate type iron sand roller combined type jet-air rice polisher has rational in infrastructure, easy and simple to handle, working stability, and dependability can be good, nominal power output height, advantage such as power consumption is low, and noise is little, and the rice that processes is fair and clear bright and clean, and broken rice rate is low, and temperature rise is low.

Below in conjunction with accompanying drawing the technical solution of the utility model is further elaborated.
