Description

Cold and hot alternation's dried bean drying-machine

Technical Field

The utility model relates to a food processing device especially relates to a cold and hot bean drying-machine in turn.

Background

In the bean curd stick making process, there is a step of drying the coagulated layer coagulated on the surface of the slurry after being dried. The just dried coacervate has high humidity and needs to be dried for a long time, and a batch of drying needs 7 hours generally. The color difference between the surface and the interior is large, the quality of the inner layer and the outer layer is uneven, the outer layer is brittle, and the inner side is hard due to a long-time drying process.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a bean curd stick dryer with cold and hot alternation, which can make the quality inside and outside the dried bean curd sticks more uniform and the color difference relatively reduced.

The utility model discloses a cold and hot alternation dried bean curd stick dryer, including the feeding zone and the discharging zone that set up at the same end, and set up the observation area at the other end, feeding zone and observation area between communicate and set up a plurality of cold and hot alternation units, observation area and discharging zone between communicate and set up a plurality of cold and hot alternation units, feeding zone and discharging zone be linked together; two ends of the dried bean curd stick dryer are communicated through a rotary conveying belt;

the cold and hot alternating unit sequentially comprises a drying zone, a cooling zone and a buffer zone from the feeding direction; the rotary conveyer belt is provided with a plurality of hooks for hanging dried beancurd sticks.

A bean curd stick drying-machine cold and hot in turn, its advantage lies in, bean curd stick hangs behind the couple, gets into each cold and hot unit in turn from the feeding district by the conveyer belt that circles round and dries in proper order. In the cold and hot alternating process, the hardening phenomenon in the dried beancurd sticks can be effectively inhibited. Meanwhile, the cold and hot alternation sequence is that the cold and hot alternation is carried out firstly and then the cold, and the next cold and hot alternation is carried out through buffering, so the temperature difference inside and outside the dried beancurd sticks is obviously reduced compared with the prior art. Because the heat is transferred inwards after the outer layer is heated, the dried beancurd sticks reach the cooling area to be subjected to surface cooling. Finally, the temperature is basically consistent inside and outside in the buffer zone. The color difference between the inside and the outside of the made dried beancurd sticks is obviously reduced, and the quality is greatly improved.

And two air heaters are horizontally arranged on one side of the drying area.

And two air coolers are horizontally arranged on one side of the cooling area.

And an air brake is arranged between the drying area and the cooling area.

And an observation window or an electronic camera is arranged at the position of the observation area, which is opposite to the rotary conveying belt.

Detailed Description

As shown in FIG. 1, the utility model relates to a bean curd stick drying-machine of cold and hot alternation, including feeding zone 10, drying zone 12, cooling zone 13, buffer 14, observation area 15, drying zone 12, cooling zone 13, buffer 14 and the ejection of compact district 11 that convolution set up. The feeding area 10 and the discharging area 11 are communicated with each other, and all the areas are communicated and penetrated through by a rotary conveying belt 20. The rotary conveying belt 20 is provided with a plurality of hooks 21, the dried beancurd sticks are hung on the hooks 21 and then sequentially enter from the feeding area 10 through the rotary conveying belt 20, then reach the observation area 15 after passing through the two cold and hot alternating units, and reach the discharging area 11 after passing through the two cold and hot alternating units, at the moment, an operator can judge whether to perform next drying circulation on the dried beancurd sticks according to the drying condition acquired in the observation area 15, if not, the dried beancurd sticks are taken away from the discharging area 11, otherwise, the rotary conveying belt 20 can automatically bring the dried beancurd sticks into the next circulation.

In order to achieve better heating effect, two hot air blowers 31 are horizontally arranged on the outer side of the dried bean curd stick dryer in each drying area 12, an air inlet pipe of each hot air blower 31 passes through the dryer, and then air is exhausted into the drying area 12 to heat the dried bean curd sticks. Because the temperature reduction process follows, the temperature range of the temperature-increasing gas can be selected to be larger, such as 40-70 ℃.

Similarly, for better cooling effect, every cooling zone 13 all levels in the dried bean dryer outside and sets up two air-coolers 32, and the intake pipe of air-cooler 32 is earlier through the desicator, and then the gas is arranged into cooling zone 13 and is cooled down the dried bean. An air lock 33 is arranged between the drying zone 12 and the cooling zone 13 for temperature isolation. The temperature of the cooling gas can be selected within the range of 10-30 ℃ in cooperation with the temperature selection of the previous step.

The observation area 15 just can set up the observation window of naked eye or set up electronic camera 34 and cooperate the host computer to handle in the position to revolving round conveyer belt 20, if carry on the host computer and handle then not the utility model discloses an improve the scope, the utility model discloses only need restrict electronic camera 34's the position that sets up, how to judge the dry condition through the video signal is prior art, is field technical personnel's common general knowledge.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
