Abstract

The utility model provides a novel energy-saving pomace drying device, which is capable of drying pomace and comprises a rotary cylinder drier, a material returning device and a secondary steam recycling device. The rotary cylinder drier is indirectly heated by steam pipes and forms certain inclination to a horizontal plane. Pomace in the novel energy-saving pomace drying device is lifted, stirred, heated and dried by the steam pipes while passing the indirect type rotary cylinder drier, and moves along with rotation of a rotary cylinder towards a lower end of the drier to be finally complete dried prior to being discharged. The material returning device solves the problem of adhesion of high-humidity and high-viscosity materials during drying, and the secondary steam recycling device consisting of a steam ejector pump effectively utilizes secondary steam in the pomace materials so as to reduce drying energy consumption and cost. The novel energy-saving pomace drying device has the advantages of simple structure, operational reliability, low drying energy consumption and cost and capability of continuously drying high-humidity high-viscosity fresh pomace materials in batch.

Background technology

Contain a lot of valuable ingredients such as sugar, protein, fiber and fat in the pomace after fruit is squeezed the juice, can be used as fibroid food, animal feed etc., but, must after super-dry processing, can effectively utilize its value because fresh pomace water content height is difficult to store, transport.At present, the dry equipment commonly used of pomace is direct-heating type rotary drier, percolation belt dryer, paddle formula drier, tray dryer etc., and these pomace drying equipments commonly used exist following problem: the sticking wall problem during (1) dry materials; (2) the heat energy utilization rate is low, production cost is high, is difficult to large-scale promotion; (3) the inhomogeneous and product of product drying is vulnerable to the flue gas pollution problems.

Summary of the invention

When solving this low value dry materials of pomace, high energy consumption, expensive, easy sticking wall, easily contaminated and reduce the problem of product quality, the utility model provides a cover steam pipe indirect heating type revolving drum pomace drying device, this drying device not only can continuous large batch of dry high-moisture pomace, the secondary steam of evaporation when solving the ubiquitous material adhesion problems of same category of device and can effectively utilize pomace dry, improve the heat energy utilization rate, reduced drying cost.

The technical scheme that its technical problem that solves the utility model adopts: novel pomace energy-saving drying equipment goes out vapour case, discharger, distribution auger, underground auger by the steam pipe indirect and with rotary drier, feeder, indirect steam that horizontal plane forms certain gradient, rises glassware, returning charge auger, steam jet pump, steam admission case, vavuum pump, support roller, gear wheel and travelling gear and constitute; It all is that movable sealing connects that indirect steam goes out that being connected of vapour case and drier left end cap and working steam admission case be connected with right end cap.Steam jet pump is connected with the steam inlet that indirect steam goes out the outlet of vapour case, additional high energy steam inlet and working steam admission case respectively by pipeline; Discharger with distribute auger, underground auger, rise glassware and be connected one by one successively with the returning charge auger.Distribute the hand of spiral of auger opposite at two side directions of discharger, the spiral of a direction will be finished dry a part of pomace material and send and become product, and another closely descend the spiral of auger direction will finish extremely underground auger of dry another part pomace mass transport.

Fresh fruit slag enters feeder by charge door to be mixed with the dry pomace of returning charge, mixes the pomace moisture content and reduces, and has avoided the sticking wall problem of material in drier.Mixed pomace enters rotary drier, is heated by steam pipe.Material is subjected to doing with cylindrical shell elevate a turnable ladder, stirring, heating and the dry effect of the steam-heating pipe of synchronous gyration in rotating cylinder, material moves to lower discharge end from higher feed end by means of the gradient of drier simultaneously, final pomace is discharged from discharger, finishes the overall process of dry materials.At the discharger place by distributing auger that a dried pomace part is told with the form of product, another part successively by underground auger, rise glassware, the returning charge auger enters the returning charge mouth.The high energy steam of replenishing enters steam jet pump by the high energy steam inlet mixes with the indirect steam that goes out the vapour case from indirect steam, forms dry required working steam.Working steam enters working steam admission case by steam inlet pipe successively, enters the sleeve pipe in the admission axle again, enters annular steam chest, enters the dry pomace of steam-heating pipe at last.Then in heating tube, flow out in the collect cavity through the condensed condensed water of heat exchange, enter water chamber through outer Y-pipe again, discharge from condensation-water drain by the inclination of revolving drum itself.

The utility model has the advantages that, solved the problem of easy adhesion in the high sticking high moisture material drying by returning charge to dry pomace, by utilization once more, improved the thermal efficiency of pomace drying equipment simultaneously, reduced the pomace drying cost pomace evaporation secondary steam.This utility model is simple in structure, and cost of manufacture is low, is suitable for promoting in the production unit of various dry scales.
