Abstract

The invention discloses a wet cassava pulp storage process, which comprises the following steps of: 1, performing surface film coverage and bagging on just produced wet pulp in a wet pulp production place to prevent the wet pulp from contacting air so as to avoid overoxidation; 2, opening the bagged wet pulp in a processing place, adding into a pulp chest with a filter net and filtering; 3, removing massive fibers, fat and proteins from the filtered wet pulp by using a disc centrifuge; 4, injecting the separated wet pulp into a wet pulp storage tank, and adding a food-grade 0.01 percent sodium hydrogen phosphate solution staying on the surface of the wet pulp into the wet pulp storage tank; and 5, during use, pumping the wet pulp into a pulp mixing tank, and adding deionized water for blending to reach a soft flow state. The wet cassava pulp storage process effectively solves the problem that wet cassava pulp is easy to deteriorate and difficult to store, massive wet pulp can be purchased from the wet pulp production place at one time to be stored, cassava demand quantity is increased greatly, the enthusiasm of farmers for growing cassava is improved, and the income of the farmers is increased.

Description

Cassava wet pulp storage technology

(1) technical field:

The present invention relates to a kind of cassava wet pulp storage technology.

(2) background technology:

At present, Guangxi part tapioca(flour) source mill, preparatory gelatinization tapioca(flour) source mill adopt the cassava wet pulp to produce.But because the cassava wet pulp is apt to deteriorate, (placement flavescence souring more than 4 days in the normal temperature air is produced required gelatinization point and raise, and wastes energy to be difficult to a large amount of storages; Product viscosity, whiteness, visco-elasticity, resistance to deterioration all do not reach industry quality standard), therefore can only order to wet pulp factory by the starch prods turnout of every day.So reason then causes cassava wet pulp factory mass production easily, and the result is that the cassava demand can not roll up, and cassava price can't improve to increase farmers' income; And cassava fails to adopt pressing in time to dig in season; Cause the cassava powder containing quantity to descend, the cassava price glides, and farmers' income reduces.

Existing comparatively ideal cassava wet pulp storage way is freezing with the freezing storehouse, but present the no large-scale refrigerator chamber in Guangxi, and freezing required costly, adds return freight, and cost is per ton will to increase by 270 yuan, so refrigerator chamber refrigerates wet pulp and do not have an exploitativeness.

(3) summary of the invention:

The purpose of this invention is to provide a kind of cassava wet pulp storage technology that solves the perishable difficult storage problem of cassava wet pulp.

Can realize the cassava wet pulp storage technology of above-mentioned purpose, accomplish through following step:

The wet pulp of 1, in the wet pulp grown place harsh output being come carries out that surface film covers, pack, avoids the wet pulp ingress of air and over oxidation causes the glycase ramp, the wet pulp phenomenon that very easily occurs turning sour, and the transportation and the short-term that are beneficial to wet pulp are stored.

2, packaged wet pulp is opened in the stock tank that drops into the tool filtering net in the back and filtered adding the building site.

3, the wet pulp after the filtration is separated through disk centrifuge again, removes wherein a large amount of fiber, fat and protein, and this is the committed step of slowing down wet pulp flavescence souring.

4, the wet pulp after separating is injected wet pulp storage pond, adds concentration in the wet pulp storage pond again and be 0.01% food grade ten hydrogen phosphate dihydrate sodium solutions, make this solution stop (coverings) surperficial in wet pulp.In the said ten hydrogen phosphate dihydrate sodium solutions with wet pulp in part acid; Prevent the too fast souring of wet pulp; And this solution has better oxidation-resistance, can better prevent the quick oxidation flavescence of wet pulp, guarantees that the pre-gelatinized starch of producing has better viscosity, whiteness, visco-elasticity and resistance to deterioration.

5, produce when taking wet pulp, wet pulp is evacuated in the pond of sizing mixing, the adding deionized water is allocated, and reaches to be prone to can use after the flow state.

Said wet pulp storage pond height is no more than 2.85m, presses together to prevent the wet pulp post precipitation, and the heat of generation can't comparatively fast be distributed, and causes the internal layer wet pulp jaundice souring phenomenon to occur.

Said ten hydrogen phosphate dihydrate sodium solution overburden depths are 30cm～40cm.

When former usefulness ten hydrogen phosphate dihydrate sodium solution PH＜6.4, more renew the 0.01% ten hydrogen phosphate dihydrate sodium solution of joining.

Said de-ionized electrical conductivity of water is less than 25, and pH value is between 5～7.

Advantage of the present invention:

Cassava wet pulp storage technology of the present invention efficiently solves the perishable difficult storage problem of cassava wet pulp, can a large amount of wet pulps of disposable buying store from the wet pulp grown place, self is produced successively carry out; Increase self processing output; Also enlarge the turnout of wet pulp grown place on the other hand, the cassava demand is rolled up, improved the enthusiasm of peasant planting cassava; Increase farmers' income, effectively drive the development of local rural economy.

(4) embodiment:

Cassava wet pulp storage technology of the present invention is carried out according to the following steps:

1, this step is being carried out in the wet pulp grown place; Be the wet pulp that harsh output is come to be carried out surface film cover, pack; Avoid wet pulp in transportation, to be exposed to the air over oxidation because of wet pulp as far as possible; Cause the glycase ramp, the phenomenon of turning sour very easily appears in wet pulp, makes more difficulty of wet pulp storage.

2, after process unit transports wet pulp back, all do not open sack, filter but packaged wet pulp is opened in the stock tank of putting into the tool filtering net according to the stock tank capacity.

3, this step is the key of slowing down wet pulp flavescence souring, and the wet pulp after the filtration is separated through disk centrifuge, removes a large amount of fiber, fat and protein in the wet pulp.

Can adopt model is the disk centrifuge branch of DHC/DRY-500, and the treatment capacity of this separating machine is 10 tons/hour.

4, the wet pulp of separating through disk centrifuge is injected wet pulp storage pond through pipeline; And in wet pulp storage pond implantation concentration be 0.01% food grade ten hydrogen phosphate dihydrate sodium solutions in the wet pulp surface, the degree of depth of ten hydrogen phosphate dihydrate sodium solutions is 30cm～40cm.

Said wet pulp storage pond is designed as follows: each wet storage stock tank (length * wide * height) is of a size of 6.5m * 6.5m * 2.85m, and (volume is 120.4125m ³, hold 186.64 tons of wet pulps, 1.55 tons of average every cube of wet pulps).

When detecting ten hydrogen phosphate dihydrate sodium solution PH＜6.4, change 0.01% ten hydrogen phosphate dihydrate sodium solution again.

The applicant unit produces 20,000 tons of preparatory gelatinization tapioca(flour)s now; Need 40,000 tons of cassava wet pulps; Be scaled 9.52 ten thousand tons of fresh cassavas (needing 2.38 tons of fresh cassavas to calculate), directly, effectively drive North Sea agro based economic development for the peasant brings 7,140 ten thousand yuan of economic benefits by average production wet pulp per ton.
