Embodiment 1

[0011] Embodiment 1. The weight ratio of main components of biomass briquettes: 20-95 parts of straw, 2-60 parts of starch.

[0012] Its production process is shown in Figure 1, including straw, crushing, sieving, starch, hydrolysis, paste making, mixing, molding, and drying processes.

[0013] Process description

[0014] 1. Straw: Use corn, rice, wheat, cotton, various plant straws, rhizomes, furfural residue, sugar residue and organic waste, at least one of them.

[0015] 2. Crushing: use a pulverizer.

[0016] 3. Sieving: pass through a 10-120 mesh sieve, and take the granulated powder under the sieve.

[0017] 4. Starch: use at least one of corn, potato, sweet potato and various plant fruit starches and degenerated starches.

[0018] 5. Hydrolysis: add water according to the ratio of starch: water = 1:5-40, the amount of water added is related to the molding method and raw materials.

[0019] 6. Paste making: Put the hydrolyzed starch into a heater with stirring, heat...

Embodiment 2

[0023] Embodiment 2. The weight ratio of main components of biomass briquette: 60-80 parts of straw, 10-60 parts of starch, 0-10 parts of preservative, 0-10 parts of flame retardant, and 0-10 parts of waterproofing agent.

[0024] Its production process includes straw, crushing, sieving, starch, hydrolysis, paste making, additives, mixing, molding, and drying processes.

[0025] Process Description

[0026] Additives refer to preservatives, flame retardants and waterproofing agents, and the number of varieties added is related to raw materials and production seasons.

[0027] All the other procedures are the same as Example 1.

Embodiment 3

[0028] Embodiment 3, the weight ratio of the main components of biomass burning incense: 60-80 parts of straw, 3-9 parts of starch, 1-3 parts of waterproofing agent, 1-3 parts of flame retardant, and 0-2 parts of fragrance.

[0029] Its production process flow is the same as example 2, and the operation description is the same as example 2.

Abstract

The invention pertains to a forming process of biomass fuel, which is characterized in that the invention is formed by preparation of components and the technique processing and the weight ratio of main components are that: straw of 20-95, and starch of 2-60. The production technique process comprises the straw, grinding, sieving, starch, hydrolysis, forming starch paste, compounding, molding and drying processes. 10-120 meshes are sieved; Hydrolyzed starch / water=1 / 5-40; the molding adopts a pouring of mould vibration or an extrusion molding; a drying temperature ranges from 1-150 DEG C. The process has the advantages of simple technique, low investment, fast effect, low cost, convenience to popularize, and also the more ideal molding method of utilizing plant straws, fruits, rhizomes and organic refuse.

Description

technical field [0001] The invention relates to a biomass fuel molding method, which is a biomass fuel molding method using plant stalks, rhizomes, fruits and organic waste as main raw materials. Background technique [0002] At present, the development and utilization of biomass fuels are very important at home and abroad. Japan developed a rod-shaped biomass fuel molding machine in the 1950s, and the United States also developed a biomass molding fuel in 1976. In 1980, my country also developed a screw-type straw molding machine, but due to the large energy consumption of the molding equipment, easy damage, low production efficiency, high cost of the produced molding fuel, and the large dust in the production process, the operating environment It is not good to wait for the reason, so far it has not been pushed away. [0003] In recent years, with the improvement of farmers' living standards, straw is no longer the necessary energy for farmers' lives. Most of the straw is ...
