Processing method and roasting device of bamboo slices for mahjong mats

Abstract

The invention discloses a mahjong mat bamboo chip processing and roasting device guaranteeing the processed bamboo chips having no color differences. The device is characterized by including steps of feeding, primary heating, dehumidifying and drying, heating in an advanced manner, coloring preparing, coloring, color determining, cooling naturally, and coloring completing. The device comprises a frame; the frame is provided with a cylinder driven by power to rotate, a heating mechanism, an air exchange mechanism exchanging the air inside and outside the cylinder and a control mechanism; the radial section of the cylinder is a regular pentagon or hexagon or heptagon or octagon; the side wall of the cylinder is provided with the inlet and outlet; the cylinder is provided with a temperature sensor; the control mechanism controls the power, heating mechanism and the air exchanging mechanism according to the temperature detected by the temperature sensor. The method can be implemented, the occupation is small, occupation of large amount of fields for bamboo chip basking is omitted, the method is environment-friendly, chemical additive adding can be avoided, finished products are free of toxic, operation and control are easy, color is modulated evenly, full automatic control can be implemented, the bamboo chips made of different materials are colored consistently, manual sorting is omitted, the product qualified rate is increased, and labor cost is saved.

Description

technical field [0001] The invention relates to the preparation of a mahjong mat, in particular to a processing method and a frying device for bamboo chips used in the mahjong mat. Background technique [0002] In the scorching summer, the mahjong mat made of bamboo slices has become a must-have "magic weapon" for citizens to enjoy the cool air. The processing method of existing mahjong mats with bamboo chips is as follows: remove the heads, tails and cores of the newly felled moso bamboo for five years, then process them into bamboo strips with the same width and thickness with a machine, and then cut the bamboo strips with saw blade equipment. The strip is sawed into a fixed length, and then the lace is processed by tools; then the two sides of the small bamboo pieces are drilled with a drilling machine; Under high pressure, a layer of hard carbonized particles will be formed on the surface of bamboo. On the surface of bamboo mat after carbonization, the hard carbonized p...

Problems solved by technology

The labor intensity is high, the cost is high, and the color of the whole mat is uneven

In order to increase sales, most mats with very uniform colors on the market are dyed or dyed, or the two processes of "carbonization + dyeing" are used, which is not environmentally friendly, but also leaves harmful substances to the human body, causing people to be infected with various diseases.
