Microwave thawing and defrosting provides an efficient processing solution for butter and other frozen dairy products. With fast and uniform microwave heating, frozen butter can be rapidly tempered or defrosted from the inside out, significantly shortening thawing time while reducing uneven heating and excessive surface softening.
The microwave system can be adjusted according to different butter block sizes, initial temperatures, target temperatures, and production capacities. It is also suitable for cheese, cream, margarine, and other frozen food materials, making it an ideal solution for butter processing, dairy production, bakery ingredients, food manufacturing, and other industrial applications.
Our industrial microwave thawing and defrosting machine provides an efficient solution for frozen butter and other frozen food materials. Microwave energy generates heat directly inside the frozen material, enabling rapid and uniform tempering or defrosting while significantly shortening processing time and reducing excessive surface softening.
The microwave process allows frozen butter blocks to be brought to the required processing temperature more evenly, helping improve temperature consistency and production efficiency for subsequent cutting, mixing, blending, or other processing steps. The system can be customized with different microwave power levels, conveyor speeds, temperature settings, and control functions according to the butter block size, initial temperature, target temperature, required processing capacity, and production requirements. It can also be used for cheese, margarine, cream, meat, seafood, and other frozen food products.

Fast and Efficient Thawing
Microwave energy directly penetrates frozen butter blocks and generates heat inside the material, significantly shortening thawing and tempering time compared with conventional methods.
Uniform Thawing
Microwave volumetric heating allows frozen butter to be heated more evenly from the inside and outside, helping reduce temperature differences between the surface and the center.
Reduced Surface Softening
Rapid microwave thawing helps minimize excessive surface softening while the center of the butter is still frozen, providing more consistent conditions for subsequent processing.
Controlled Target Temperature
Microwave power, conveyor speed, processing time, and temperature can be adjusted according to the initial temperature, butter block size, and required final temperature.
Continuous Industrial Production
The conveyor-type design enables continuous feeding and discharging, making the machine suitable for medium and large-scale butter processing and food production lines.
Improved Processing Efficiency
Rapid and controlled thawing helps prepare frozen butter more efficiently for subsequent cutting, mixing, blending, baking, or other production processes.
Easy Operation and Automatic Control
The system can be equipped with PLC and touchscreen control for convenient parameter setting, temperature monitoring, and continuous production management.
Customizable Production Capacity
Machine size, microwave power, conveyor width, and production capacity can be customized according to butter block dimensions, initial and target temperatures, throughput requirements, and production conditions.
The 3600 × 1000 × 800 mm microwave thawing chamber is constructed with 2 mm thick SUS304 brushed stainless steel, featuring a durable and food-grade design. Large inspection and cleaning doors with viewing windows allow easy observation, cleaning, and maintenance. The doors are equipped with microwave choke structures and safety interlocks to minimize microwave leakage and automatically cut off microwave power when opened, ensuring safe operation.
The microwave suppressor is made of 3 mm thick high-purity aluminum with 1.0 mm suppression plates. It has a length of 2000 mm and an opening height of 150 mm. Inductive comb-type suppression plates combined with microwave-absorbing materials effectively minimize microwave leakage, maintaining leakage levels below 5 mW/cm² when measured 5 cm from the equipment.
The inlet and outlet conveyor frames are constructed with welded stainless steel tubes and removable stainless steel covers for easy inspection and maintenance. The system is equipped with securely installed drive components, stainless steel support rollers, and a microwave-compatible plastic chain plate conveyor belt, ensuring smooth, stable, and reliable continuous material conveying.
This industrial microwave thawing and defrosting machine is designed primarily for the rapid and uniform tempering and defrosting of frozen butter blocks. Microwave energy penetrates the frozen butter and generates heat directly inside the material, significantly shortening thawing time while helping reduce temperature differences between the surface and the center and minimizing excessive surface softening.
The continuous conveyor system supports stable feeding and discharge and can be integrated into butter processing, dairy production, bakery ingredient and food manufacturing lines. Microwave power, conveyor speed, processing time and temperature can be adjusted according to the butter block size, initial temperature, target temperature and required processing capacity. The system can also be used for cheese, margarine, cream and other suitable frozen food materials.
