Description

Watermelon grain and coconut tree peeling machine

Technical Field

The utility model relates to a starch processing equipment technical field especially relates to a west millet coconut palm decorticator.

Background

Evergreen arbor of sago palm (English name: Metroxylon sagu). The stem is single-grown up to 10-20 m, and it grows from the base of the stem and mostly sprouts, while the sheath surrounding the petiole has hard thorns and gradually grows and loses, so it can be divided into two types, i.e. "thorns" and "no thorns". The leaves are feather-shaped and green, are rather similar to coconuts, the petioles are thicker, the upper parts of the leaves are concave and convex, the lower ridge parts of the leaves grow thorns, and 3 more leaves cluster together. The panicle is large and growing, and most of the light red flowers, male and female plants, grow. Is wrapped by yellow brown glossy scale, and the fruit is as big as plum. Moose deer plus islands and babu new-guinean islands native to indonesia.

The shoots are large starch storage organs. After the stem is extracted for 2.5-3.0 years, starch is accumulated from the base part of the stem and gradually pushed to the top part, and after 6-8 years, a large amount of starch is accumulated in the middle part of the stem except the topmost part.

Before the flowering period, the trunk is cut down, and the proper harvesting period for collecting starch is adopted. The yield of starch of a single stem of a good variety can reach 120-260 kg, the yield of the wild species is only 0-70 kg, the yield of starch of the sago palm tree per hectare can reach 10-15 tons, and the yield is inconsistent according to the difference of the variety, the soil in the field and the underground water level.

At present, no equipment in the domestic starch processing industry has a tree peeling function, and a crusher and a file grinder in the domestic industry crush blocky materials and do not have the tree peeling function.

The Chinese patent CN200420011056 is a rasping machine, which rapidly rasps and crushes the block material into fine powder through the fine saw teeth of the saw blade component. Chinese patent CN200620120495.2 is a direct-connected rasping machine, which is basically similar to the above patent. All of these crushers and rasps crush lump materials. The motor power of the rasping machine is relatively large, and the energy consumption is high.
