MJY Continuous Low Temperature Vacuum Belt Dryer MJ series automatic vacuum liquid/solid continuous belt dryer is a new concept of vacuum dryer, with high efficiency and energy saving drying equipment, it is developed by our technical personnel after comparison of the advantages and disadvantages of traditional spray drying and freeze drying.

Shanghai MINJIE SDR Evaporator for High Efficiency and Energy Eaving Since MINJIE successfully developed SDR energy-saving concentrator, it has been widely concerned by pharmaceutical, food, chemical, biological, environmental protection and other industries, which solves the problem of large steam consumption and high energy consumption of traditional single-effect....

On March 15, 2023, the 26th China International Food Additives and Ingredients Exhibition and the 32nd National Food Additives Production and Application Technology Exhibition (FIC) was grandly opened in Shanghai National Convention and Exhibition Center. Chairman of Shanghai Minjie led the pharmaceutical &food dryer sales team to participate in the exhibition. At the exhibition, vacuum belt dryers, vacuum low-temperature dryers, ultra-low temperature vacuum evaporator and energy-saving evaporator displayed in Hall 2.1H, attracting many domestic and foreign visitors to visit the booth to negotiate with advanced drying and evaporation solutions.

Shanghai MINJIE Dryer Manufacturer in FIC Shanghai 2023 With 1,519 exhibitors and over 52,000 visitors in 2023, Food Ingredients China (FIC) is the largest and most authoritative international show in the food additives and ingredients industry in Asia. The three-day event offers conferences and technical seminars with the latest news on food science and...

Principle of low temperature concentration technology of fruit juice

Fruit Juice Low Temperature Evaporator Heat sensitive liquid materials require concentration at low temperature (20-50℃) Fruit juice concentrate a large amount of water from the fruit juice after squeezing the fruit into the original juice. Although the nutritional value of fruit juice is not rich, it also contains a lot of dietary fib...

for high nickel ternary cathode Precursor

Vacuum belt dryer is a continuous high-efficiency &low energy dryer. The number multi-layer drying belt can be set according to the capacity of materials. The temperature is from 40 to 180℃, and the running rate can be adjusted.

Features: Complete continuous feeding and discharging under vacuum drying; High yield; The drying chamber of the product does not contact with metal, and the appearance is not damaged after drying. The drying process is easy to optimize and can be adjusted. Low energy consumption; Suitable for mass continuous automatic production.

Advantage of Vacuum belt dryer

Magnetic foreign body
The contact material is PP/PET material conveyor belt to avoid the contact between material and metal.

Moisture content
Moisture content of discharge product is low and stable, fluidity is very good, loose without agglomeration

Crystallographic Form
The material evaporates statically on the conveyor belt without destroying the crystal form

Over-drying powder
Stable heating, no over- drying powder phenomenon

Energy Consumption
Low energy consumption, energy saving and environmental protection

Capacity
Continuous production and large processing capacity

The Key Process of Ternary Material Precursor -Introduction of Filtration, Washing and Drying Equipment

Filtering and Washing Equipment
Filtration and washing equipment is to achieve solid-liquid separation of the precursor slurry obtained by the reaction, and then wash the obtained precursor cake with washing liquid to remove the sulfate, chlorine, sodium ions etc which remain in the cake.
Filtration and washing equipment mainly include filter press, centrifuge, microporous filter, filtration and washing “two-in-one” equipment.

Drying Equipment
The selection of material precursor needs to consider at least the following points:
The moisture content requirements of the product;
The moisture content of filter cake and whether the water content of filter cake is uniform;
Dryer’s production capacity, material feed mode;
Dryer and ternary material precursor contact part of the material need to be alkali resistant, and can not be brought into metal impurities or other impurities;
The drying temperature that needs to be achieved.
The precursors of ternary materials can be dried by hot air circulation oven, rotary dryer, disk dryer, rake dryer, microwave dryer, etc. But the vacuum low-temperature belt dryer can avoid metal pollution with efficient drying time.

Low-Temperature Vacuum Belt Dryer Features:
Effective control of magnetic foreign bodies and metal impurities in terminal products
During the whole drying process, the material is in a relatively static state to preserve the crystal shape of the product to the greatest extent
Continuous drying, gradient heat transfer, all on-line parameters controllable
The drying time is short (60-150min) at the temperature allowed by the product (40-250℃)
Clean, pollution-free production conditions and online recovery of organic solvents (continuous drying, closed system, effective in-place cleaning)
Drying under vacuum environment, reducing the entry of carbon dioxide, ensuring the product quality

Shanghai MINJIE sincerely thank you for all of your support in the previous year, wish everyone the Rabbit year of 2023 has began with prosperousness, success and happiness.

Lithium Hydroxide Monohydrate & Carbonate Drying Process

Lithium Hydroxide Monohydrate & Carbonate Drying Machine More and more new energy industries pay attention on drying process for their products, such as: Lithium salts: lithium hydroxide monohydrate &anhydrous lithium hydroxide drying Ternary precursor & High nickel ternary cathode material drying Cobalt

is an important ingredient in vegan products. However, how to extract high purity, high quality plant protein suitable for human digestion, for example extract from almonds, sunflower seeds or quinoa, multiple process steps are required. One of the challenges is the final .
Normally a protein manufacturer needs a drying machine for the final process step: drying the protein powder, and this machine must be able to achieve optimal drying at low temperatures. In addition, the solvents can also be recycled. For solvent evaporation at the end of the process, a with a dynamic drying process is suitable.This way there is no nesting of particles and the proteins are dried evenly and thoroughly. The automatic control device continuously measures and adjusts the temperature, the temperature decreases through this process, and can be adjusted for different products. Vaporized solvents are collected and fed back into the process -- both conserving resources and reducing costs.
SHANGHAI MINJIE has become a leading of & since established in 1998.

Vacuum belt dryer turn traditional static drying to vacuum dynamic drying, reduce drying time from 10-20 hours to 30-60 minutes. In vacuum belt dryer, the drying temperature is adjustable for different products. It solves the high temperature problem with spray dryer and denaturation problem due to long drying time with traditional drying oven. Colors, solubility, ingredients preservation of the dry product from vacuum belt dryer are incomparable.
