Jam is a gelatinous substance, it is called fruit sauce, which is made of fruits, sugars and acidity regulators and uses more than 100 °C. Making jam is a way to preserve fruit for long time. Jam is mainly used on bread or toast. In order to ensure that the jam can be eaten directly and the nutrients are not lost, it is very suitable for the method of low temperature thawing.

No matter what small fruits such as strawberries, blueberries, grapes, rose fruit, large fruits such as plum, orange, apple, peach can also be made into jam. Only one fruit is used at the same time. Colloids are used in sugar-free jams, cheap jams or special jams (eg durian, pineapple). Colloids commonly used in jams include: pectin, bean gum and sanxian gum.


Microwave jam thawing equipment is to slow down the temperature of the frozen jam to 3-4 degrees by microwave.Becouse of the dielectric constant of the material is very low after the water becomes ice.The microwave of the frequency is 2450 MHz that can directly penetrate the material with a thickness of about 10 cm. It is rapidly heated to achieve the purpose of microwave thawing. In this respect, the thawing speed of the microwave thawing technology is significantly higher than the conventional thermal thawing equipment.

Advantages of LD1705 jam low temperature microwave thawing equipment:

The LD1705 low temperature microwave thawing equipment directly acts on the whole seabuckthorn fruit that needs to be thawed by the microwave generated by the magnetron through the waveguide and the microwave. The microwave is deepened into the interior for heating and does not require a heat conduction process, thereby achieving simultaneous heating inside and outside, greatly saving thawing time and improving production efficiency.

At the same time, the whole body I is kept in a closed environment by sealing arrangement of the feed port 11 and the discharge port 12. This not only ensures that the nutrition of seabuckthorn is not damaged and the fruit is not corrupt during the thawing process, but there is no danger of microwave radiation when working and it does not pollute the environment. The utility model has the advantages that the design is reasonable, the structure is simple, the thawing is uniform, the speed is fast, the synchronization is good, the production is efficient, the maintenance is simple, the sea buckthorn whole fruit can be thawed without crushing, no nutrient loss, no pollution and deterioration. . The temperature rises from the deep freezing temperature (below -19~- 22C°) to the freezing point temperature (about 0~-4C°).

Working principle of LD1705 low temperature microwave thawing equipment:

LD1705 low temperature microwave thawing equipment is composed of a sealed body 1 and a microwave heating device disposed on the body I and a conveyor belt 2 disposed in the body 1.The microwave heating device is used for heating and thawing the whole fruit of the seabuckthorn on the conveyor belt 2so that the surface is simultaneously subjected to the action of the electromagnetic field to generate heat.

The uniformity of thawing is good, and the phenomenon of external heat and internal cooling does not occur, so that the whole fruit of seabuckthorn can be directly thawed without being broken and thawed again. The microwave heating device includes a magnetron 3 that is disposed outside the body 1 and a microwave release port 4 that is uniformly disposed above the inside of the body 1. The microwave release port 4 is connected to the microwave transmitting end of the magnetron 3 by the waveguide 5. The microwave is generated by the magnetron 3, it is conducted through the waveguide 5.The microwave is irradiated onto the material by the microwave discharge port 4. Conical reflectors 6 are disposed above the conveyor belt 2 with the microwave release opening 4 as an apex. The reflector 6 is made of metal, the inner layer is coated with a non-magnetic material, and the bottom is at a distance of more than 5 cm from the conveyor belt 2.

In the preferred embodiment, taking two microwave release ports 4 and two reflectors 6 as an example, the microwaves can uniformly and centrally heat the seabuckthorn through the action of the reflector 6, thereby improving the freezing efficiency and saving energy consumption.

LD1705 low temperature microwave thawing equipment

The magnetron of the LD1705 low temperature microwave thawing equipment is connected to the high-voltage transformer through the circuit board to increase the energy required to generate the microwave.A cooling fan is arranged on one side to cool the magnetron. The bottom connection of the reflector is provided with an infrared temperature measuring device connected to the circuit board, the temperature of the seabuckthorn is measured to feed back to the magnetron, thereby precisely controlling the time and temperature of the thawing.
