The AMW100 allows deep frozen foods to be tempered or defrosted (butter only) quickly such as meat, poultry, fish, fruits, vegetables, cheese, butter, etc…
The distinctive features of the AMW 100 are the use of a sliding table & a large pneumatic door making easier loading and unloading of 1 block and equally its turn table & its microwave coupling system by two ways above and below the product.
ADVANTAGES
FAST: very short time of treatment, less than 10 minutes, high production flexibility;
EASY TO USE: rolling tray for loading / unloading, pneumatic door movement, PLC with colour touch screen;
ECONOMIC: product gain from 5 to 10 %, continuous flow operation, minimum floor space, fast return on investment;
HOMOGENEOUS: use of a turn table, microwave power inlets above and under the product, cross coupling of microwaves and built-in proprietary structures for the uniform repartition of microwaves;
RELIABLE: very good control of final temperature;
HYGIENIC: no bacteriological growth, complies with all hygiene regulations and standards, keeps taste and texture qualities;
FLEXIBLE: can be used for tempering of meat, fish, vegetables, packed (carton without metallic staple or plastic film) or not packed.
MAIN APPLICATION
FOOD INDUSTRY APPLICATION
• Tempering
KEY BENEFITS
DESIGN
• Very compact equipment with a small footprint
• Large pneumatic door
TECHNOLOGY
• 915 MHz microwave optimized designed chamber (with a special modelisation software)
• Microwave distributed on the right side, from the top and the bottom of the chamber
CONTROLS
• HMI 7” with remote control (quick intervention possible from a long distance)
• USB and ethernet connexions
TEMPERING CAPACITIES
The AMW 100 offers has a tempering capacity between 125 kg/h and 200 kg/h from initial -18°C to final temperature -4 °C/-2 °C. The final temperature of – 4 °C /-2 °C is the average temperature measured just after the microwave treatment.
This capacity is variable and depends on the final required temperature, on the product type (meat, fish, vegetables, fruits, butter etc.) its shape and its fat concentration. The charts in the following pages show the figures.
The data in the charts below are calculated operating the AMW 100 at 5 kW microwave power with ton/toff*optimum, for blocks with regular size and weight (25 kg, 600 mm x 400 mm x 150 mm) and for an initial temperature around -18 °C.
*ton/toff is the microwave utilization within 1 hour including loading/unloading and door opening/closing; the optimum is 85 %.
OBSERVATIONS
If fatty products are to be processed, fat ought to be very homogeneously distributed in the block, otherwise the final temperature for good tempering homogeneity is limited at -4 °C;
At -4/-2 °C the blocks are at the optimum temperature for processing: dicing, grinding, cutting, slicing…
The maximum microwave power which can be used in tempering is limited by the products and not by the AMW. Recipes power vs. time must be chosen according to the compromise between capacity and homogeneity of heating.
TEMPERING CAPACITY VS. DESIRED FINAL TEMPERATURE
Example: Chicken ≃ 270 kg/h from -18 °C to -5 °C or ~ 170 kg/h from -18 °C to -3 °C
Example: Fatty pork ≃ 310 kg/h from -18 °C to -5 °C or ~ 225 kg/h from -18 °C to -3 °C
It has to be noted that starting at -18 °C has almost no effect on the AMW capacity if initial temperature is homogeneous in the whole product.
