Pecan outer skin shell charcoal and its processing method

Abstract

The present invention is pecan shell charcoal and its production process. Pecan shell is produced into machine made charcoal to utilize resource fully and eliminate environmental pollution. The pecan shell charcoal consists of pecan shell charcoal 40-80 wt% and wood powder charcoal 20-60 wt%. the production process of the pecan shell charcoal includes the following steps: 1) drying the material to water content of 8-12 % and crushing to size below 3 mm; 2) mixing material; 3) forming the mixed material in rod making machine into required shape; and 4) carbonizing.

Description

technical field

[0001] The invention relates to charcoal and a processing method thereof, in particular to hickory nut shell charcoal and a processing method thereof. Background technique

[0002] The main producing area of ​​hickory in China is Lin'an in Zhejiang Province, and the output accounts for 70% of the whole country. After the pecan fruit is picked from the tree, the outer skin of the fruit needs to be peeled off first, and then it is fried and processed, and the walnut kernel after removing the inner shell can be eaten; the outer skin is discarded because it has no use value, and it is left to rot naturally , Weathering decomposition. Because the shell of hickory nuts is alkaline and the skin is thick and difficult to decompose, it has been seriously polluting the local environment and has become a problem in environmental protection; especially in the season of picking hickory nuts, the pollution is even more serious. On the other hand, as a kind of resource, h...

Examples

Embodiment 1

[0020] Embodiment one: by weight percentage hickory nut shell shell powder 50%, charcoal 50% mixes and stirs evenly through rod making machine high temperature and high pressure (about 310 ℃ of its temperature, pressure is 450n / mm 2 ) is plasticized and formed into raw materials for semi-finished machine-made charcoal. The shapes include cylindrical, prismatic, square, coal cake, etc., which are purified by dry distillation at 900°C for 76 hours, and naturally cooled for 68 hours after smoke removal, and transformed into smokeless, odorless, and non-toxic. clean charcoal.

Embodiment 2

[0021] Embodiment two: 80% of hickory nut shell powder by weight percentage, 20% of charcoal are mixed and stirred evenly (about 320 ℃ of its temperature, pressure is 500n / mm through rod making machine high temperature and high pressure 2 ) is plasticized and formed into semi-finished raw materials for mechanical distillation of charcoal. The shapes include cylindrical, prismatic, square, and coal cakes. Non-toxic clean charcoal.

Embodiment 3

[0022] Embodiment three: by weight percentage hickory nut shell powder 40%, charcoal 60% mixes and stirs evenly through rod making machine high temperature and high pressure (about 300 ℃ of its temperature, pressure is 400n / mm 2 ) is plasticized and formed into raw materials for machine-made charcoal semi-finished products. The shapes include cylindrical, prismatic, square, coal cake, etc., which are purified by dry distillation at 850°C for 72 hours, and naturally cooled for 60 hours after smoke removal, and transformed into smokeless, odorless, and non-toxic. clean charcoal.
