Corn flour dry-mixing mechanism

Abstract

The invention discloses a corn flour dry-mixing mechanism, which comprises a corn kernel grinding device and a powder mixing device sequentially from front to back according to a technical process. The corn kernel grinding device comprises a grinding unit, a drying unit and a return unit sequentially according to a technical process. The grinding unit comprises a grinding tank, a rotating shaft, adecontaminating mechanism, an upper grinding mechanism and a lower grinding mechanism, and the decontaminating mechanism, the upper grinding mechanism and the lower grinding mechanism are arranged inthe grinding tank. The top of the grinding tank is provided with a feeding port and an upper insertion port allowing vertical insertion of the rotating shaft, and the bottom of the grinding tank is provided with a discharging port. The powder mixing device comprises a mixing tank and an upper mixing cover which covers the mixing tank, and a cavity of the mixing tank is provided with a first mixing screen plate, a first mixing chamber, a second mixing screen plate and a grinding / mixing integrated chamber sequentially from top to bottom. The corn flour dry-mixing mechanism has advantages of guarantee of produced corn flour quality, effectiveness in mixing of corn flour and wheat flour and less proneness to caking and blockage.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a cornmeal dry mixing mechanism. Background technique [0002] Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop, and it is also the crop with the highest total yield in the world. Due to high yield, good quality and strong adaptability, the cultivated area of ​​corn has developed rapidly. After the corn is harvested, the corn needs to be peeled off, and then the corn cobs are placed in an open field to dry, so that the corn cobs are dried to a certain extent and then threshed to obtain corn kernels. [0003] Corn flour is one of the deep-processing products of corn kernels. Corn flour contains a large amount of lecithin, linoleic acid, grain alcohol, vitamin E, cellulose, etc. It has various health effects such as lowering blood pressure, lowering blood fat, anti-arteriosclerosis, preventing ...

AI Technical Summary

Problems solved by technology

However, generally in food processing, the amount of production is relatively large. The above-mentioned high-efficiency flour mixing and sifting device adopts arc-shaped stirring blades installed in the stirring box for stirring. If the stirring box is set too small, the production efficiency will be low. If the mixing The box is set too large, and it is difficult to mix the powder evenly only by the stirring effect of the arc-shaped stirring blades

[0007] The patent application 201520766551.9 discloses a flour raw material mixer, which has two feeding mechanisms, which are located on both sides of the top of the mixing chamber, and can be loaded with different materials, such as flour and vegetable powder, and then mixed by the mixing mechanism. Mixing. There are three groups of mixing blades in the mixing mechanism, which are respectively distributed on the upper, middle and lower parts of the stirring rod, which can fully mix the flour. The mixed flour falls from the outlet of the mixing bin to the sieve, and then Enter the vibrating sieve through the sieve, because of the vibration of the vibrating sieve, the flour mixture falling on the sieve is sieved through the sieve, and easily enters the inside of the vibrating sieve, and is evenly mixed again under the action of the vibrating sieve, and becomes looser , which is convenient for later kneading; however, the feeding mechanism adopts a screw propulsion device. During the feeding process, due to the extrusion between the materials, the powders are more dense, and it is difficult to mix the raw materials after entering the mixing chamber. , easy to agglomerate, which affects the mixing effect; although it improves the mixing effect by setting multiple sets of mixing blades, when the mixing chamber is too large, the effect is limited, and the problem of powder agglomeration cannot be solved, which affects subsequent production and processing
