Summary of the invention
To the above-mentioned deficiency of prior art, the technical problem that the present invention will solve provides a kind ofly makes the forming agent content oxidation ignition dope, inorganic low environmental protection type inflammable barbecue charcoal and working method thereof without industrial chemicals.
The technical scheme that addresses the above problem is: this environmental protection type inflammable barbecue charcoal; In block form or clavate or sphere or honeycomb cheese; Form by following raw materials according and weight part proportioning thereof: the outer peel powdered carbon of 95-105 part bamboo charcoal powder and/or wood charcoal powder and/or machine-made carbon sticks powder, 2-10 part dry fruit, 15-25 part mildew-resistant α starch paste, 0.5-1 part wood powder, 0-1.5 part clay; Water ratio 2-5%, burning time 15-60 second.
The working method of this environmental protection type inflammable barbecue charcoal is carried out as follows:
(1) gets the raw materials ready: substandard products charcoal, broken charcoal in A, purchase bamboo charcoal or charcoal or the machine-made carbon sticks; It is subsequent use less than the powdered carbon of 80 orders (promptly the thickest carbon granule is 80 orders) to be ground into granularity, B, purchase or self-control dry fruit outer peel charcoal, and it is subsequent use less than 100 purpose powdered carbons to be ground into granularity; C, purchase or self-control wood powder; Granularity is subsequent use less than 50 orders, D, collection clay, and it is subsequent use less than 80 orders soil powder to be ground into granularity; The preparation of E, mildew-resistant α starch paste: with α starch: the part by weight of water=1: 4, add the Na that accounts for the above two gross weight 2-3% 2CO 3Mixing makes in 60-80 ℃, and is subsequent use;
(2) mixing of raw material: the material of getting ready with step (1); Mix by weight ratio; Earlier with 95-105 part bamboo charcoal powder and/or wood charcoal powder and/or machine-made carbon sticks powder and 2-10 especially the pericarp powdered carbon mix; Add 0.5-1 part wood powder and 0-1.5 part clay powder and mix stirring, add mildew-resistant α starch paste 15-25 part again, stir;
(3) ageing: the compound of step (2) is displayed 5-10min;
(4) compression moulding: the demoulding after the compression moulding in piece shape or clavate or sphere or gaufre formation type die;
(5) dry solidification: carry out mechanical drying or kiln drying to water ratio 2%-5%, be finished product;
(6) packing: pack with plastic bag sealing.
The invention has the beneficial effects as follows without industrial chemicals and make the oxidation ignition dope, when burning is smokeless, no sulphur is smelly and does not have nitride release; Inorganic forming agent addition is few, and the useless quarrel in combustion back less and can back to the field to use no environmental sanitation future trouble; Be prone to light, combustion heat value is high, do not influence foreign exchange earning.
Embodiment
The present invention below will combine embodiment to make further detailed description: earlier raw material and weight part proportioning thereof are listed in the table below by 8 embodiment:
Embodiment 1 (embodiment 1 corresponding raw material and weight part proportioning value thereof in the synopsis):
The granularity of getting the raw materials ready and require in (1) set by step that should pulverize in each raw material, mildew-resistant α starch paste is by the said method preparation of the E that gets the raw materials ready.Earlier 45 parts of bamboo charcoal powder, 50 parts of wood charcoal powders and 10 parts of machine-made carbon sticks powder and 2 parts of dry fruit outer peel powdered carbons mixing are mixed thoroughly; Add 1 part of wood powder and mix thoroughly, add 25 parts of mildew-resistant α starch pastees at last, after stirring; Display 5-10min; In the Honeycomb briquet machine of mechanism, be pressed into honeycomb cheese charcoal for roasting, kiln inner drying to water ratio 3%, 45 seconds kinds of burning time.
What need explain here is that machine-made carbon sticks generally is fired into bamboo and wood bits material; Expand thus; The powdered carbon of the charcoal of firing with various biological raw materials all can be made main body material of the present invention but consider the charcoal that plant straw, leaf, grass blade etc. are fired, and it is high that calorific value is owed, so do not mention specially.
Dry fruit outer peel powdered carbon is meant the powdered carbon that at least a outer peels such as walnut, Semen Caryae Cathayensis, oil tea, paulownia seed, Chinese torreyanut, coconut are fired, and is preferred with the powdered carbon of the high dry fruit outer peel of oleaginousness.Because of this type outer peel powdered carbon contains more easy volatile material; Help reducing the burning-point of main body material; Through burning weight loss and exothermicity test comparison; The time that the weightless peak value of this type outer peel charcoal and exothermic peak occur is bamboo charcoal powder, wood charcoal powder and machine-made carbon sticks powder significantly already all, more early than pulverized anthracite, explain that dry fruit outer peel kindling temperature is low, ignites soon.
