Description

A kind of aquatic product drying equipment

technical field

The invention relates to a drying equipment for aquatic products, which belongs to the field of drying equipment.

Background technique

my country has a long coastline and rich fishery resources. In Zhejiang Province alone, there are more than 1 million tons of dried aquatic products every year, and the electricity consumption reaches 400-500 million kWh. Due to the high water content and high protein content of aquatic products, the muscle fibers will gradually shrink and be closely connected during the drying process. Therefore, the traditional hot air drying makes the outer layer of aquatic products crusted, which is not conducive to water evaporation, slow drying speed and huge energy waste (heat The gas is directly discharged into the atmosphere). In addition, if the drying temperature is too high, it will cause fat oxidation and Maillard browning, resulting in bad smell and great damage to heat-sensitive ingredients, which will seriously affect the quality of the product. The use of microwave drying and vacuum drying consumes a lot of energy, and the input and operating costs are relatively high. Therefore existing drying method is unfavorable for the development of aquatic product dried product industry. It is also a problem that needs to be solved urgently.

An aquatic product drying equipment, including a fan, a drying chamber, a solenoid valve, a throttle valve, a first evaporator, a liquid storage tank, a condenser, a drying machine room, a compressor, a water tank, a first centrifugal fan, a second evaporator, Heating wire, partition and second centrifugal fan, the drying chamber is provided with a partition, the heating wire is installed under the partition, the first centrifugal fan and the second centrifugal fan are installed under the drying chamber, and three centrifugal fans are installed on the right side of the drying chamber. Fan, drying machine room is installed outside the left side of the drying room, there is a gap on the left side of the drying room, and the second evaporator and condenser are arranged outside the gap; compressor, condenser, liquid storage tank, solenoid valve, throttle valve, the second One evaporator is cyclically connected through pipelines to form a heat pump system; the second evaporator is connected to the pipeline between the liquid storage tank and the compressor, and the second evaporator works in parallel with the first evaporator; the first evaporator is installed on the The upper outside of the dryer room.

The second evaporator is connected to a water tank through a water pipe, and the water tank is installed at the lower part of the dryer room.

The first centrifugal fan is located on the left side of the bottom of the drying chamber, and the second centrifugal fan is located on the right side of the bottom of the drying chamber, forming a forced circulation air duct with each other.

The condenser is on the left side of the second evaporator, and both are on the same plane and the same height.

Described guide plate is provided with two, is installed in drying room by rotating shaft, and has 50cm away from fan, and two guide plates vertically carry out three equal parts of drying room.

The advantages of the present invention are: the high-efficiency heat pump dehumidification system is designed ingeniously, and the moisture removal amount per unit power consumption is effectively improved through the heat exchange of the cold and hot air streams. With the same input power, more water can be removed, and a forced circulation system has been designed to increase the water output rate per unit power consumption of aquatic product drying equipment, which should have a broad market space.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in the figure, an aquatic product drying equipment includes a fan 1, a drying chamber 2, a solenoid valve 3, a throttle valve 4, a first evaporator 5, a liquid storage tank 6, a condenser 7, a drying room 8, and a compressor 9. Water tank 10, first centrifugal fan 11, second evaporator 12, heating wire 13, partition 14 and second centrifugal fan 15, a partition 14 is provided in the drying chamber 2, and an electric heater is installed under the partition 14 Silk 13, the first centrifugal fan 11 and the second centrifugal fan 15 are installed below the drying chamber 2, three fans 1 are installed on the right side of the drying chamber 2, and a drying machine room 8 is installed outside the left side of the drying chamber 2, and the left side of the drying chamber 2 is opened. There is a gap, and the second evaporator 12 and the condenser 7 are arranged outside the gap; the compressor 9, the condenser 7, the liquid storage tank 6, the solenoid valve 3, the throttle valve 4, and the first evaporator 5 are sequentially connected through pipelines , constituting a heat pump system, through which the first evaporator 5 quickly absorbs the heat energy from the outside, and at the same time heats the internal air through the condenser 7, killing two birds with one stone; the second evaporator 12 is connected between the liquid storage tank 6 and the compressor 9 On the pipeline, low-temperature condensation and dehumidification are realized, and the absorbed heat energy does not flow out, but is supplied to the condenser 7 for subsequent heating, so the dehumidification heat drying efficiency is high; the second evaporator 12 and the first evaporator 5 work in parallel; The first evaporator 5 is installed outside the upper part of the dryer room 8 for external heat absorption.
