Description

TECHNICAL FIELD

[0001] The utility model relates to food machinery technical field, concretely relates to a kind of oil bean skin peeling device. BACKGROUND

[0002] Oil bean skin is thin food formed by the surface coagulation of soybean milk, which can be used as raw material for making yuba. In the prior art, soybean milk is transported through a slurry conveying channel. During the transportation process, oil bean skin is coagulated on the upper surface of the soybean milk. However, the initial coagulated oil bean skin is too thin, which is not conducive to processing and has poor taste. The conventional method to increase the thickness of oil bean skin is to increase the length of the slurry conveying channel to prolong the transportation time and increase the coagulation time of oil bean skin. However, this method requires a larger space for the equipment, which is extremely costly. Another method is to spray soybean milk on the oil bean skin. However, the surface thickness of the oil bean skin formed by this method is not uniform, and the amount of soybean milk that can be carried on the surface of the oil bean skin is limited, which still cannot meet the thickness requirement.

[0010] Further, the bottom of the conveying belt is provided with a lifting roller in the width direction, and a longitudinal cutter is overlapped on the lifting roller to cut the oil bean skin in the length direction.

[0011] Further, a folding column is arranged behind the lifting roller, and the cut oil bean skin is shaped into a column by the folding column, and a groove roller is arranged behind the folding column to carry and forwardly convey the column-shaped oil bean skin.

[0012] Further, a twisting rod is arranged behind the folding column, and a sliding rod is connected to the twisting rod, and the sliding rod is arranged in a sliding channel and can reciprocate in the transverse direction in the sliding channel to drive the twisting rod to twist the oil bean skin on the conveying belt.

[0013] Further, a horizontal top conveying belt is connected to the end of the conveying belt, and a drying machine and a cooling fan are arranged on the top conveying belt.

[0014] Compared with the prior art, the beneficial technical effects of the oil bean skin peeling device are as follows:

[0015] The lifting mechanism is arranged in the middle of the pulp conveying groove, so that the pulp conveying groove is divided into two parts, and one layer of oil bean skin is condensed on each side, and the two layers of oil bean skin are overlapped and then enter the next process, so that the thickness of the oil bean skin made in this way can meet the requirements and is relatively uniform, and the length of the equipment does not need to be increased and can even be appropriately shortened, and a certain amount of soybean milk liquid can be carried between the two layers of oil bean skin, which is more conducive to increasing the thickness.
