Description

A kind of even membrane cylinder drying equipment

The utility model relates to a kind of food baking machinery, especially the drying equipment of being made up of cylinder, feed mouth and scraper.

Drum drying equipment be by the cylinder that rotates in heat conducting mode, the hot surface that the liquid phase material cloth of needs oven dry is applied to cylinder makes a kind of continuous drying machinery of material water evaporates.Widely used in the market drum drying equipment, its structural shape is full water vapour or heat conduction wet goods heat medium to be fed the cylinder of hollow and material is heated, the cloth of material is coated with mode splash device or feed mouth all is installed below single cylinder, adopt splashing type or immersion type cloth film, though it is convenient that these two kinds of cloth film modes have the cloth film, the characteristics of features simple structure, but they all exist the cloth non-uniform film thickness even, the material gelatinization degree is not high, be difficult to prevent the solid piece in the viscous food, and seriously influence oven dry food mouthfeel and quality.

The purpose of this utility model provides a kind of cylinder drying plant that is applicable to multiple liquid phase food material, and not only the cloth film is even for it, effectively prevents the formation of solid piece in the food, makes even, the consistency of thickness of oven dry food tissue; And slurries had good gelatinization effect.

In order to achieve the above object, a kind of even membrane cylinder drying equipment that the utility model provides, it comprises a cylinder, and the scraper and the feed mouth that are positioned at the cylinder surface outside, described feed mouth is positioned at the top of cylinder cylinder, is equipped with forward extrusion roller and reverse compression roller outside the cylinder cylinder.

After adopting such structure, because a plurality of forwards, reverse compression roller have been installed on the cylinder cylinder, on the one hand compression roller make slurries successively cloth be coated with and the cloth film thickness along the complete uniform distribution of whole drum length direction, more be applicable to the food processing of various viscosity, comprise food such as cereal, pulp matter; On the other hand, the rubbing squeezing action of compression roller itself has prevented the formation of agglomerate in the food effectively, and it is consistent to make slurry mix evenly, organize; Again because compression roller has formed capaciting material groove each other, be positioned at outspoken the connecing from this capaciting material groove feed of last direction of feed on cylinder cylinder top, the slurries in the capaciting material groove are subjected to the heat effect of cylinder, make it to obtain abundant gelatinization, fully sterilization, reach ready-made cooking effect, improved end product quality greatly.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of a specific embodiment of a kind of even membrane cylinder drying equipment of the present utility model.

The cylinder 4 of even membrane cylinder drying equipment shown in Figure 1, gear wheel 3, hinge wheel 2 all are installed on the main shaft 15, main shaft 15 is supported on the frame 16 by spindle drum 14, main shaft 15 is a hollow shaft, so that inject saturated vapor (or conduction oil) and discharge condensed water in the cylinder 4 of hollow.Be meshed with gear wheel 3 by electric motor driven driving gear 1, thereby rotate in the lump by main shaft 15 drive cylinders 4, hinge wheel 2.Cylinder 4 is one to be of a size of the casting cylinder that ∮ 1500 * 2250 operating pressures reach 0.8MPa, surface plating network, casting cylinder can tolerate high pressure, can overcome the yielding defective of welded drum again, the gelatinization effect that the high temperature that high pressure roller produces also improves drying rate and realizes ideal.Forward extrusion roller 5 has three all to place the cylinder 4 cylinders outsides abreast, and with the rotation direction opposite (identical) of cylinder 4 to the slurries force direction, the pinion 6 that is installed on forward extrusion roller 5 one ends is meshed with gear wheel 3; Forward extrusion roller 5 is A3 steel axles of three ∮, 240 * 2250 appearance chromium plating, and the working clearance of itself and cylinder 4 can be done corresponding fine setting to adjust the cloth film thickness.Forward extrusion roller 5 and reverse compression roller 9 have formed three gelatinization grooves on the cylinder of cylinder 4, on the one hand constantly the compression roller that rotates make slurries 8 more equably cloth be applied on the cylinder of cylinder 4, the rubbing effect of its rotation simultaneously can prevent the formation of agglomerate effectively; On the other hand, be subjected to the effect of precooking of high temperature cylinder 4, slurries 8 gelatinizations in the gelatinization groove are more abundant, and the mouthfeel of oven dry food is more crisp.Oppositely compression roller 9 also is the hollow roll shafts of a ∮ 240 * 2250 chrome faced A3 steel, it places the cylinder 4 cylinders outside abreast, and it is identical with the rotation direction of cylinder 4, the minor sprocket 10 that is installed on compression roller 9 one ends in the same way links by sleeve-barrel roollr chain 13 and hinge wheel 2, and oppositely the effect of compression roller 9 is the material weirs are gone up and formed on slurries 8 anti-cylinder 4 surfaces that are applied to.The knife face of scraper 11 is close to the surface of cylinder 4, continuously to strike off the product contents film 12 of oven dry from cylinder 4 surfaces, scraper 11 upper supports have adjusting screw(rod), make it to be close to cylinder to regulate scraper pressure, scraper adopts the 65Mn steel plate to carry out Carburization Treatment, its hardness 〉=HRC60.Feed mouth 7 is equipped with constantly to infeed slurries 8 in the gelatinization groove in the cylinder top of cylinder 4, has overcome the bottom feed and can't realize the defective of even feed and pre-gelatinization.
