How to choose a biological tissue embedding machine?

First, there are many reasons for leaking wax or wax. There are many reasons for leaking wax. There are two main reasons for the leakage of wax:
(1) The manufacturer's testing method is wrong. There is a virtual soldering condition in the main wax bath welding. It should be detected by diesel or liquid paraffin. The water soldering test usually cannot find the virtual solder joint. This will cause the water to be detected normally and the paraffin wax will appear when the wax is added. The permeability of paraffin is 8.5 times stronger than water! Old manufacturers basically use water testing, the reason is cheap, save trouble. It’s not something that is not made in China, but the detection method of the old manufacturer is wrong.
(2) The temperature probe of the wax inlet and temperature sensor of the solenoid valve is not well sealed on the main wax cylinder. Most manufacturers only add a rubber mat to prevent the penetration of paraffin, but they did not expect that the rubber will tear the rubber seal while the nut rotates and the tearing rubber ring is impossible to leak wax. Based on commercial technology considerations, the materials and methods used by Huida in this regard cannot be specified here. Please forgive me!
(3) The flow of wax is not just like a man who has a serious prostate. The reason why the wax is not only stopped is because the solenoid valve of poor quality is selected, the solenoid valve can not be completely closed after the power is turned off, and the wax is not stopped; there is also a case where the impurities in the paraffin block the normal closing of the solenoid valve. As long as the quality of the solenoid valve and the addition of the second stage is the paraffin precipitation filter function can basically be solved.

Second, the capacity is small . The small-capacity embedding machine will have a phenomenon of cracking of the wax block when slicing, and it will be re-embedded when the crack occurs. This is a poor performance of paraffin wax. In the past, waxing was added to the paraffin to improve the toughness of the paraffin. : Paraffin wax can improve the toughness of paraffin after repeated heating. The capacity of the embedding machine is large. The remaining paraffin will be heated and melted again. After repeated several times, the toughness of paraffin can be improved, so there is no need to add beeswax. Huida's embedding machine adopts the world's largest capacity design, up to 6900 ml, which solves the problem of cracking of wax blocks.

Third, the embedding machine has a fire. The fire in the embedding machine is mainly caused by the wax leakage and the time relay. The contact of the relay will automatically disconnect when the temperature reaches the set temperature. When the temperature drops to the set temperature, it will pick up again. The paraffin temperature is generally above 60 °C, and the relay contacts will have an electric spark when they are sucked. If the leaking paraffin drops near the relay, it is easy to cause a fire! Therefore, it is recommended to purchase a buried machine with contactless heating technology.

Fourth, the workbench is hot. This is a manifestation of the inhumanity of many products (including imported products) in product design. Especially in the summer, the technicians have to be carefully embedded. The heating device of the workbench should be closed during the work. After the completion of the embedding work, it is heated to melt the residual paraffin on the countertop and then automatically recover it.

Seed Cleaner & Grader becomes basic and popular grain seed cleaning equipment in recent years. It helps farmers effectively clean grain harvested from ground. Seed cleaner & grader is used to remove oversize impurity, undersize impurity, light impurity from grain seed. Besides this, it also can grade cleaned seeds to different size ranks. From sesame, wheat, paddy, to soybean, kidney bean, groundnut, Seed Cleaner Cum Grader has wide application.

We have different Grain Cleaning Machine models. Capacity ranges from 3 ton per hour to 20 ton per hour. Each model has its particular feature. We will suggest client suitable model for particular seeds. Grain seed cleaner driving power is 3 phase electricity. We can customize grain cleaner base on different electricity specification for clients worldwide.

Grain cleaner has reliable running, convenient screen replacing and maintenance.

Seed cleaning machine working procedure: Raw material is fed from the Bucket Elevator, then elevator transfer raw material to the wind sieve (air screen). In wind sieve, the straw, smashed pieces, dust and Other light impurity is sucked out by air blower. After air cleaning, raw material is delivered to sieving trunk. Sieving trunk has several sieve layers. From top to bottom layer, the sieves holes are from big to small. There are vibration motors on both sides of the sieve trunk. While grain cleaning machine started, the sieving trunk begin vibration sifter. Seeds falling on first layer then go through several sieve layers. First layer sieve will remove the big impurity, final sieve layer sieve will remove the small impurity. Middle layers can be used to remove either big, small impurity or grading the cleaned seeds by size difference. Different layer material has different outlets. Finally clients get cleaned and graded grain seeds.
