Description

Waterfall coating machine for top coating with particulate slurry

Technical Field

The utility model relates to a waterfall coating machine for top coating particulate slurry.

Background

As the existing mature food production equipment, the waterfall type coating machine is mainly used for the work of pouring chocolate paste, jam paste or syrup on a blank body during the production of foods such as ice cream or cakes, cereal bars and the like. The conventional waterfall type coating machine at present mainly comprises a food blank conveying mechanism, a material cylinder, a stirring mechanism, a lifting pump and a waterfall spray head which are arranged on a frame. The food embryo conveying mechanism mainly adopts a net belt conveying mechanism, and a plurality of feeding rollers driven by a motor drive a steel wire net belt to circularly run so as to convey the food embryo. The material jar is fixed in the frame bottom, and its inside is equipped with the whipping roller as rabbling mechanism, and this whipping roller is used for stirring and the mixing of thick liquids by external transmission drive. The material cylinder is sequentially connected with the lifting pump and the waterfall nozzle through pipelines and is used for lifting the slurry to the waterfall nozzle above the steel wire mesh belt to form slurry waterfall, and the slurry waterfall is cast on the food embryo body which is conveyed forward.

However, the existing waterfall type coating machine is very easy to cause the problem that slurry is adhered to the bottom of a food blank when the food with strict top coating requirements is poured and coated, so that the due attractive appearance of the food is damaged, and the problem is that:

1. the pore structure of the steel wire mesh belt used for conveying food embryo bodies on the existing waterfall type coating machine is extremely easy to adhere to slurry flowing onto the pore structure. When the upper layer steel wire mesh belt passes through the slurry waterfall, the slurry quickly flows into the pores of the steel wire mesh belt, and is difficult to clean. Even though some devices are provided with scrapers for scraping the slurry on the steel wire mesh belt rotating to the lower layer, the cleaning effect is poor. When the part of the steel wire mesh belt is turned back to the upper layer again, the sizing agent is adhered to the bottom of the subsequent food blank, so that the food has an undesirable bottom coating problem.

2. Due to the lack of separation between the upper layer and the lower layer of steel wire mesh belts, when the upper layer of steel wire mesh belts pass through a slurry waterfall, slurry can pass through the holes of the steel wire mesh belts, or the edges of the steel wire mesh belts directly drip onto the lower layer of steel wire mesh belts after being cleaned by a scraper, so that the slurry adhered on the lower layer of steel wire mesh belts is further thickened. And when the steel wire mesh belt rotates to the upper layer again, the bottom of the food blank is polluted, and the food appearance is affected.

In addition, with the continuous improvement of the taste requirements of people on the coated foods, the types of the coated foods are also continuously developed. At present, a kind of ice cream products have rich and popular taste due to the addition of nut, cheese, sugar and other particles into the pure chocolate paste. However, such foods also suffer from the following problems when produced using the conventional waterfall coating machine described above:

1. the lift pump in the existing waterfall coating machine adopts a vane type centrifugal pump, the pump is easy to break and grind particles when the slurry with particles is conveyed, the final coating taste is affected, and when more particles are in the slurry, the pump also has the risk of blockage, so the pump is not suitable for conveying the slurry with particles.

2. The stirring roller in the material cylinder of the existing waterfall coating machine consists of a central shaft and a plurality of stirring blades which are distributed radially, and the stirring roller can play a good role in beating and stirring pure fluid slurry, but has poor stirring effect on slurry with particles, cannot form fluidity, the particles tend to be deposited at the bottom of the material cylinder easily, and are difficult to be fully and uniformly mixed with the slurry, so that the distribution uniformity of the coated particles on the surface of the final food is very poor, and the look and feel of the food are affected.

For example, a synchronous belt transmission device adopts a motor speed reducer set with an output shaft for fixing a main synchronous belt pulley, and the main synchronous belt pulley is connected with a secondary synchronous belt pulley fixed at one end of a feeding screw rod through a transmission belt.

Furthermore, the frame is also provided with a vibrating cam which is abutted against the lower surface of the upper layer of round belt and a vibrating cam driving motor which drives the vibrating cam to rotate. The vibration cam is used for beating the upper layer circular belt so as to accelerate slurry on the upper layer circular belt to shake off into the dripping hopper.

Further, the round belt driving device comprises a motor speed reducer unit, a driving sprocket fixed with an output shaft of the motor speed reducer unit, a driven sprocket arranged on the frame and connected with the driving sprocket through a chain, a main round belt pulley coaxially arranged with the driven sprocket, and a plurality of auxiliary round belt pulleys arranged on the frame and matched with the main round belt pulley to drive the round belt to circularly operate.
