Abstract

Materials including lignin powder, millet flour, wheat bran, vegetable oil, potassium dihydrogen phosphate, rice bran, ammonium bicarbonate, diammonium phosphate, dry yeast and water are placed into reactor, standing at 63-67 deg.C for 90 hr with once stirring each 4 hr, mixed with NaOH to regulate pH value to 12-13, standing at 84-88 deg.C and 1.5 atm for 2 hr with once stirring each 30 min, mixed with HCl to regulate pH value to 6 and separated to obtain liquid, i.e., humic acid. The said process is easy to control and can obtain product with stable quality.

Description

Processing technology for biochemical humic acid

The present invention relates to a kind of production technique of biochemical humic acid.

The production technique of biochemical humic acid belongs to the dry method zymotechnique, and main raw material is: sawdust, wheat bran, bean powder, vegetables oil, bicarbonate of ammonia, sesame paste etc.Its production technique is a mixing, and proving room is put in pack (every bag of 25kg), and temperature is controlled at 30 ℃, and overturning in 7 days is once taken out in proving room after 15 days.Add NaOH, stir, transferring pH value is 13, places then 24 hours, adds HCl, stirs, and transferring pH value is 6, places 12 hours.Pressure extrusion, solid-liquid separation is isolated the liquid that contains humic acid 0.8-1.7%.The shortcoming of this production technique is that labour intensity is big, and the production cycle is long, influenced by natural temperature, and production technique is wayward, unstable product quality, and yield is low, the product cost height, and be not suitable for large-scale industrial production.

The object of the present invention is to provide a kind of with short production cycle, labour intensity is little, production technique is easy to control, constant product quality, yield height, the biochemical humic acid technology for mechanized production that cost is low.

Purpose of the present invention is achieved through the following technical solutions: A, with wood powder, Semen setariae powder, wheat bran, vegetables oil, potassium primary phosphate, rice bran, bicarbonate of ammonia, diammonium phosphate, dry yeast, put into reactor, stir after adding water, heat temperature raising kept 90-100 hour to 63-67 ℃, stirred once in per 4 hours, the each stirring 3-7 minute, after treating that insulating process finishes, add NaOH, acid adjustment basicity pH value is to PH12-13; B, heat temperature raising are to 84-88 ℃, and plus-pressure kept 2 hours under this temperature and pressure to 1.5kg, stir 5 minutes, and add HCl acid adjustment basicity to PH6 in per 30 minutes; C, carry out solid-liquid separation and get liquid.

Each component content (weight percent): sawdust 76-78%, Semen setariae powder 4.8-5.2%, wheat bran 7.5-9%, vegetables oil 3.2-3.8%, potassium primary phosphate 0.7-0.82%, rice bran 1.5-1.6%, bicarbonate of ammonia 1.9-2%, diammonium phosphate 1.5-1.6%, dry yeast 0.18-0.22%.

Calculate to produce 350 tons of stostes per year, technology of the present invention and existing processes contrast is as follows:

Existing processes needs direct labor 240 people, 72000 working dayss (1 year by calculating in 300 days), 396 hours production cycles, labour intensity is big, the difficult control of production technique, unstable product quality, yield low (0.8-1.7%), 350 tons of 266000 yuan of stoste raw materials cost (760 yuan/ton).

Technology of the present invention needs direct labor 30 people, 9000 working dayss (1 year by 300 days), 98 hours production cycles, labour intensity is little, and production technique is easy to control, constant product quality, yield height (4.5-5.6%), 350 tons of 135450 yuan of stoste raw materials cost (387 yuan/ton).

Below in conjunction with embodiment the present invention is described in detail:

Adopt following table as specific embodiment of the invention component content:

As above arbitrary group of component content shown in the table is by following explained hereafter, adopt first group of component content: wherein wood powder can adopt sawdust, A, 1520 kilograms in sawdust (76%), 104 kilograms of Semen setariae powder (5.2%), 180 kilograms of wheat brans (9%), 76 kilograms of vegetables oil (3.8%), 16.2 kilograms of potassium primary phosphates (0.81%), 30 kilograms in rice bran (1.5%), 38.4 kilograms in bicarbonate of ammonia (1.93%), 30.8 kilograms of diammonium phosphate (1.54%), 4.4 kilograms in dry yeast (0.22%), above raw material is dropped in the reactor (2000L), adding weight is that 1.8-2.4 doubly promptly adds 1.8,2.1,2.4 water doubly all can, adding 4199 kilograms of entry (2.1 times) stirs, heat temperature raising is to 63-67 ℃, be specially 63 ℃, 65 ℃, all can for 67 ℃, select 65 ℃, under this temperature, keep 90-100 hour (selecting 96 hours), stirring in every 3-5 hour once (is selected 4 hours), stirs 3-7 minute (selecting 5 minutes) at every turn, treat that insulating process finishes after, add NaOH acid adjustment basicity pH value to PH12-13(PH12, PH13, all can, select PH13); B, heat temperature raising to 84-88 ℃ (be specially 84 ℃, 86 ℃, 88 ℃ all can, select 86 ℃), by air compressor (0.6m ³) plus-pressure is to 1.5kg, keeps 2 hours under this temperature and pressure, stirs 5 minutes in per 30 minutes, stop insulating process after, add HCl acid adjustment basicity to PH6; C, put into plate-and-frame filter press (450 type 12m2) and carry out solid-liquid separation, the content of isolated liquid mesophytization humic acid is 5%, and liquid is sent into basin, and residue can be dried and be handled the back and use as feed and soil improvement agent.
