Description

Technical Field

[0001] The invention relates to the technical field of starch processing equipment, in particular to a sago coconut peeling machine. Background Art

[0002] Metroxylon sagu is an evergreen tree. The stem is solitary, up to 10-20 meters high, with many buds growing from the base of the stem. When young, the leaf sheaths surrounding the petioles have hard thorns, but some lose them gradually as they grow, so they can be divided into two types: "with thorns" and "without thorns". The leaves are pinnate, green, and quite similar to coconuts. The petioles are relatively thick, concave on the upper part and convex on the lower part, with thorns growing on the lower ridge, mostly in groups of 3. The panicle inflorescence is huge and terminal, with many light red flowers, and the plant is monoecious. It is covered with shiny yellow-brown scales, and the fruit is as big as a plum. It is native to the Molucca Islands in Indonesia and the Papua New Guinea Islands.

[0003] The stem is a huge starch storage organ. 2.5-3.0 years after the stem is drawn out, starch begins to accumulate at the base of the stem and gradually moves toward the top. After 6-8 years, a large amount of starch is stored in the middle of the trunk except for the top.

[0004] Before flowering, it is the best time to cut down the trunks and collect starch. The starch yield of a single stem of a good variety can reach 120-260 kg, while that of a wild variety is only 0-70 kg. The starch yield of each hectare of sago palm trees can reach 10-15 tons, and the yield varies with the variety, site soil and groundwater level.

[0005] At present, there is no equipment in the domestic starch processing industry that has the function of peeling trees. The crushers and files in the domestic industry are used to crush blocky materials and do not have the function of peeling trees.

[0006] Chinese patent CN200420011056 is a file grinder, which uses the fine teeth of the saw blade assembly to quickly grind and crush bulk materials into fine powder. Chinese patent CN200620120495.2 is a direct-connection file grinder, which is basically similar to the above patents. All these crushers and file grinders are used to crush bulk materials. In addition, the motor power of the above file grinders is relatively large, and the energy consumption is high.

[0007] The processing of sago coconut palm starch requires separating the core from the trunk first, and crushing the separated core to make sago coconut palm starch. However, there is no special peeling equipment in the starch processing industry, and it is not possible to peel and crush the sago coconut palm thoroughly at one time. It usually takes multiple steps to complete, which makes the starch processing process complicated, energy-intensive and cost-intensive. Therefore, it is necessary to design a sago coconut palm peeling machine to solve the problems of the existing technology and fill the gap in the domestic starch industry in this regard.
