Embodiment

[0019] Example: The slurry is pumped into the primary vertical sieve at the highest point of the process. After screening, the slurry flows into the primary net sieve for screening, and the sieved slurry flows into the raw slurry tank and enters the next process. The primary vertical sieve The slag produced by the centrifugal force falls directly into the primary filter press, and the slag is further pressed dry, so that more starch emulsion is separated from the slag. Flow into the net sieve together, continue to sieve and separate, the slurry screened out by the net sieve flows into the slurry tank, and the whey enters the raw pulp tank and enters a process. The slag pressed out of the primary filter press falls into the mixing tank, and at the same time, it is stirred with clean water, and flows into the secondary vertical sieve through the pipeline through the high-level difference for centrifugation. , used for water distribution of the primary and secondary pulverizers t...

Abstract

The invention provides a tuberous starch slurry-residue separation technique by screening and pressure filtration, which modifies slurry-residue separation procedures in tuberous starch production, and combines a vertical screen, a filter press and screen cleansing into a complete stereoscopic elevation difference technological process, wherein the vertical screen is used for separating residues from slurry by means of centrifugal force, the filter press is used for separating the residues from the slurry by means of extrusion force, and the vertical screen and the filter press in matched use can avoid the problem of poor cleanliness when tuberous residues are treated by vertical screen equipment, so that slurry-residue separation effect can be more effectively improved, feeding once is achieved, and multiple procedures including matched use of the emulsion slurry, the residues and process water, pressure drying of the tuberous residues can be completed by means of multiple screening and pressure filtration. Besides, power, automation, the amount of equipment, process water consumption and labor forces can be greatly reduced, the technique has the advantage of saving of operation cost and energy, emulsion slurry concentration is improved, starch extraction ratio is increased, and good technical effect is achieved.

Description

technical field [0001] The invention relates to a process for separating potato starch pulp and dregs, which is especially suitable for cassava starch processing. Background technique [0002] The pulp and residue separation process after cassava crushing is one of the key processes in starch production. Whether the pulp and residue separation is thorough directly affects the yield of starch. The earlier traditional pulp and residue separation process used self-made curved screens, vibrating flat screens and other equipment. These equipments use gravity to separate, and the separation efficiency is low, and the equipment is relatively heavy and occupies too much area. At present, some domestic equipment manufacturers have absorbed and digested some imported equipment, and produced a vertical pulp and residue continuous separator (referred to as vertical screen). Multi-stage washing and screening are carried out to separate solids and impurities from starch milk, which can e...
