Description

A kind of pepper drying and pepper dew extraction device

technical field

The invention relates to the technical field of processing prickly ash and prickly ash, in particular to a prickly ash drying device and a prickly ash extracting device.

Background technique

Zanthoxylum bungeanum can be used as seasoning and medicine. Zanthoxylum bungeanum can be used as a traditional Chinese medicine. Anesthetic. Pepper should be dried in time after picking. Drying has a great impact on the value of pepper, which is the key link of high quality and high price. The traditional drying method adopts the method of direct drying. This method must be dried on the day of picking, because pepper is easy to mold When drying, it should not be spread too thickly, and it must be stirred frequently. When the light is too strong, it should not be directly exposed to the sun, because the embryos of peppercorns are easy to burn, which will reduce the quality of peppercorns. This makes farmers who grow peppercorns in large areas very passive and often suffers The hazards of rainy weather, and the drying of the dried pepper is not complete, and it is easy to deteriorate during storage.

The current pepper drying method is baked in a fire pit, and the pepper is directly stacked in the earthen drying pool. The temperature distribution of this drying method is uneven, and the top is low and the bottom is high, resulting in excessive drying of the pepper at the bottom, or even paste; The hot steam in the middle is difficult to dissipate heat, so that the peppercorns in the middle are in the hot and humid steam, resulting in blisters in the middle layer of peppercorns, making it difficult to dry; the upper layer of peppercorns is heated differently from the bottom peppercorns, and when the bottom layer is dry, the upper layer of peppercorns is not dried thoroughly ; It is inconvenient to operate when taking out the pepper after it is dried, and it is necessary to scoop out the pepper with a container; therefore, it is difficult to control the drying temperature in this drying method, the quality of the pepper is messy, the storage period is short, and the operation is inconvenient.

In addition, Zanthoxylum can dispel cold and warm the stomach, relieve pain and itching, reduce swelling, and treat chilblains. The existing drying equipment does not have the equipment to collect Zanthoxylum, so that the Zanthoxylum can be directly discharged, which pollutes the environment and wastes resources.

Contents of the invention

In view of this, the purpose of the present invention is to address the deficiencies of the prior art, to provide a pepper drying and pepper dew extraction device that is convenient for loading and unloading pepper, easy to operate, and easy to control temperature, which solves the problems of uneven heating of pepper and drying efficiency. Low efficiency, long aging time, poor drying quality, uneven color, short storage time and inability to collect pepper dew, resulting in waste of resources.

To achieve the above object, the present invention adopts the following technical solutions:

A pepper drying and pepper dew extraction device, comprising an oven body, in which a pepper dew collection chamber and a drying chamber are sequentially arranged from top to bottom; the drying chamber is composed of a vertical partition Divided into at least one independent drying cavity, the drying cavity is divided into upper and lower layers by the first horizontally arranged baffle, the upper layer is the air circulation layer, and the lower layer is the material drying layer; the material drying The layer is divided into a first chamber and a second chamber for placing materials by two second vertically parallel baffles, and a first chamber is located between the first chamber and the second chamber for setting the first chamber. The third chamber of the fan; the air outlet and the air inlet of the first fan communicate with the first chamber and the second chamber respectively; a condenser is arranged in the middle of the wind circulation layer, and the condenser The two sides of the device are respectively provided with a second fan communicated with the first cavity and a third fan communicated with the second cavity;

A pepper dew collection device is provided in the pepper dew collection chamber, and a dehumidification blower and a first air valve communicated with the wind circulation layer are respectively provided on both sides of the pepper dew collection device.

In view of the above technical characteristics, multiple drying chambers are set in the drying chamber, and different numbers of drying chambers can be set according to the needs of the manufacturer. During the drying process, the appropriate number of drying chambers can be opened according to the output. For example, when the tonnage of pepper to be dried is small, the first, second, and third fans and condensers in a drying chamber can be turned on, so as to avoid energy waste, save energy, and reduce costs; each drying chamber The air circulation of the air circulation is independent of each other. Every 20-40 minutes, the wind direction of the first, second and third fans will change in order, so that the air circulation in the drying chamber is carried out alternately, so as to ensure the temperature distribution in the drying chamber. More uniform; if the wind in the first chamber enters through the air inlet of the first fan, and then is discharged to the second chamber through the air outlet of the first fan, the third fan draws the wind in the second chamber to the wind circulation layer, After passing through the condenser for heat exchange, the second fan pumps the hot air in the air circulation layer into the first chamber to form air circulation. After an interval of 20-40 minutes, the wind circulation direction is reversed; the pepper dew is collected in the pepper dew collection room. Collection, when the humidity in the drying chamber is too high, the dehumidification fan will draw the hot gas in the air circulation layer to the pepper dew collection room, and the pepper dew collection device will collect the pepper dew in the hot air in the drying chamber, and the collected Zanthoxylum bungeanum has high purity and can be used directly. At the same time, it avoids the direct discharge of hot air containing Zanthoxylum bungeanum to the outdoor polluting environment, which also reduces the waste of resources and maximizes the value of Zanthoxylum bungeanum. The gas is discharged to the air circulation layer to ensure the air pressure balance in the drying chamber, and at the same time achieve the purpose of reducing the humidity in the drying chamber and indirectly improve the drying efficiency of peppercorns; in addition, the first, second and third fans are connected in series. The way of connection makes the wind pressure in the drying chamber larger, so that the hot air passes through the gaps between the peppercorns, ensuring uniform color and good drying quality of the peppercorns.
