Abstract

The utility model discloses a rice grading cooling machine which belongs to a device separating the solid from the solid by means of sieving. A vertical type box body of the utility model is split into an upper operation chamber and a lower operation chamber. The upper box body is a sieving chamber, and a grading sieve is installed in the sieving chamber. The lower box body is a cooling chamber provided with a roller and a low-temperature blower fan. The rice is cooled by the low-temperature wind from top to bottom, and the low-temperature wind is vented from top to bottom. The rice grading cooling machine has the advantages of compact structure and good rice cooling effect, which is good for the buffing operation of the buffing machine.

Description

The cool rice of a kind of rice grading machine

Affiliated technical field:

The utility model relates to the device that solid is separated with method for sieving from solid.

Background technology:

In traditional rice processing technology, the rice from rice mill grinds out directly enters polishing machine, on the one hand because temperature drift, and the rice matter of influence polishing rice, aspect again, cracking rice of rice mill generation enters polishing machine, influences the technical-economic index of polishing machine.

Summary of the invention:

The utility model provides the cool rice of a kind of rice grading machine, makes rice be in the normal temperature state, and can reduce and crack rice and moisture content.

Solution of the present utility model is that vertical cabinet is divided into upper and lower two work-rooms, and upper box is a sieve compartment, and lower box is a cooling chamber.Classification sieve nest, classifying screen kinematic pair are installed in the upper box with the supporting of upper box support.Lower box has a cylinder with the supporting of lower box support in the lower box, slip in the cylinder from the conversion hopper from the whole grain rice of classifying screen, cooling chamber with low-temperature air-cooling but, low temperature wind from bottom to top, outside the exhaust blower shedder.Rice cools off from top to bottom, when discharging the cool rice of classification machine, reaches temperature required.

The utility model compact conformation, rice can be cooled to below 30 ℃.This machine can be installed in the rice processing technology before and after the polishing machine polishing operation.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.Among the figure: 1 lower box support, 2 discharging openings, 3 low temperature blower fans, 4 conversion hoppers, 5 classifying screen kinematic pairs, 6 classification sieve nests, 7 exhaust blowers, 8 charging apertures, 9 refining buckets, 10 upper box supports, 11 cylinders, 12 reducing motors, 13 support rollers.

The specific embodiment:

Embodiment 1: the refining bucket 9 that the utility model adopted, and classification sieve nest 6, classifying screen kinematic pair 5, basic identical with the device of the rice processing factory of 30～50 tons of present daily outputs, crack rice and separate outside the machine of discharge afterwards at sieve compartment and whole grain rice.Whole grain rice is slipped in the cooling chamber cylinder through the conversion hopper, and cylinder 11 inwalls have the deflector that flows to discharging opening, and cylinder is connected with reducing motor 12, and reducing motor is installed in the lower box outside.The other end of cylinder rolls with support roller 13 and supports.The low temperature blower fan is with the air conditioner refrigerating device of 1.5 commercially available～3P, and is installed in the discharge port end of cylinder.Exhaust blower 7 is a power less than 800 watts axial flow blower.For ease of assembling, upper and lower casing is made separately, and upper box uses lower box support 1 to support with upper box support 10 supportings, lower box, and two tanks is detachable connection.

Embodiment 2: exhaust blower 7 is not installed separately, with pipeline upper box is connected with exhausting system in the rice work flow, all the other are with example 1.
