Embodiment 1

[0021] A method for preparing charcoal for barbecue with hollyhock, comprising the following steps:

[0022] (1) Heat and dry 1 ton of sunflower sunflowers after stacking and drying. The temperature is controlled at 250°C during drying, and the sunflower sunflowers are drawn out after drying for 15 minutes. At this time, the water content of the sunflower sunflowers is 7% (by weight);

[0023] (2) the dried hollyhocks of step (1) are crushed into 4mm particles with a cutting pulverizer;

[0024] (3) Take the crushed hollyhock granules in step (2), squeeze the crushed hollyhock into the casing with a spiral extruder, and extrude into a hexagonal hollow strip at a temperature of 150°C , the speed is 35~40 seconds / piece, extrusion molding;

[0025] (4) Put the extruded hollyhock in step (3) into a carbonization furnace, bake and carbonize at 550°C for 48 hours, then seal the furnace and keep it warm for 48 hours to obtain finished charcoal, and 0.337 tons of finished product can...

Embodiment 2

[0027] A method for preparing charcoal for barbecue with hollyhock, comprising the following steps:

[0028] (1) Heat and dry 1 ton of sunflower sunflowers after stacking and drying, the temperature is controlled at 300°C during drying, and the sunflower sunflowers are drawn out after drying for 10 minutes. At this time, the water content of the sunflower sunflowers is 6% (weight);

[0029] (2) the dried hollyhocks of step (1) are crushed into 3mm particles with a cutting pulverizer;

[0030] (3) Take the crushed hollyhock granules in step (2), squeeze the crushed hollyhock into the casing with a spiral extruder, and extrude into a hexagonal hollow strip at a temperature of 300°C , the speed is 35~40 seconds / piece, extrusion molding;

[0031] (4) Put the extruded hollyhock in step (3) into a carbonization furnace, bake and carbonize at 520°C for 48 hours, then seal the furnace and keep it warm for 24 hours to obtain finished charcoal, and 0.335 tons of finished product can be...

Embodiment 3

[0033] A method for preparing charcoal for barbecue with hollyhock, comprising the following steps:

[0034] (1) Heat and dry 1 ton of sunflower sunflowers after heap drying, the temperature is controlled at 200°C during drying, and the sunflower sunflowers are drawn out after drying for 20 minutes. At this time, the water content of the sunflower sunflowers is 8% (weight);

[0035] (2) the dried hollyhocks of step (1) are crushed into 5mm particles with a cutting pulverizer;

[0036] (3) Take the pulverized hollyhock granules in step (2), squeeze the pulverized hollyhock into the casing with a spiral extrusion propeller, and extrude into a hexagonal hollow strip at a temperature of 350°C , the speed is 35~40 seconds / piece, extrusion molding;

[0037] (4) Put the extruded hollyhock in step (3) into a carbonization furnace, bake and carbonize at 600°C for 36 hours, then seal the furnace and keep it warm for 24 hours to obtain finished charcoal, and 0.325 tons of finished produ...

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, ...
