Method of preparing barbecue charcoal by using abelmoschus manihot

Abstract

The invention discloses a method of preparing barbecue charcoal by using abelmoschus manihot. The method comprises the following steps of drying an abelmoschus manihot material, crushing and pelletizing the abelmoschus manihot material, extrusion-forming, roasting and charring. According to the method of preparing the barbecue charcoal by using the abelmoschus manihot, a process design is reasonable, the operability is strong, the drying temperature and the moisture content after drying are preferably selected through a large quantity of experiments according to fiber characteristics and physical and chemical properties of the roots, stems and leaves of the abelmoschus manihot; then, the formed abelmoschus manihot charcoal is prepared by adopting a preferable extruding process; finally, the abelmoschus manihot charcoal obtained by adopting the preferable charring process is low in ash content and great in heat release. According to the method, the waste abelmoschus manihot is used as a material to change waste into things of value, so that the resource waste and the environmental pollution can be reduced, and social value and social benefits are important.

Description

technical field

[0001] The invention relates to a method for preparing charcoal for barbecue, in particular to a method for preparing charcoal for barbecue with hollyhock. Background technique

[0002] Over the past century, due to the rapid development of human society, the industrialization and urbanization of various countries and the improvement of people's living standards, human beings have seriously consumed natural resources, especially forest resources. Therefore, the application of various waste materials as fuel substitutes is a major issue. At present, there are methods of making charcoal by using sawdust, bamboo dust, chaff and sugarcane residues.

[0003] Hollyhock is resistant to drought, thinness, and waterlogging. It can be planted on barren hills, slopes, and saline-alkali land. The leaf diameter yield is 220% of the seed yield. The planting area is increasing nationwide. The extract of hollyhock flower has important pharmacological effects on nephritis, ...
