The TMW225 allows deep frozen foods to be tempered or defrosted quickly. It is adapted for products like\r\nmeat, poultry, fish, fruits, vegetables, cheese, butter, etc\u2026<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The distinctive feature of the TMW 225 is the use of the microwave technology to achieve the best tempering homogeneity while maintaining a good microwave efficiency.

The large size of the cavity, the length under microwaves and the crossed coupling of microwaves above and below the blocks are a few examples of the solutions used to conciliate capacity, efficiency and homogeneity.

Possibility to choose the direction of operation and to install the generator on a platform.<\/p>\n\n\n\n

TEMPERING CAPACITIES<\/h2>\n\n\n\n

The TMW225 offers a tempering capacity between 6 t\/h and 9 t\/h from -18 \u00b0C to a final temperature of – 4 \u00b0C \/ – 2 \u00b0C in 95% of the block, which is the optimum temperature for processing: dicing, grinding, cutting, slicing\u2026 The capacity is calculated to temper frozen blocks with standard dimensions 600 mm x 400 m x 200 mm and a weight of about 20 \/ 25 kg. If fatty products are to be processed, fat ought to be very homogeneously distributed in the block, otherwise the limit temperature for homogeneity is -4 \u00b0C.

The tempering capacity is variable and depends on the final required temperature and on the product (meat, fish, vegetables, fruits, butter, etc. Figures below show these variations. The data in the charts are calculated for the TMW225 operating at 180 kW power, with ton\/toff 1 optimum at 95 %, for blocks with regular size and weight 25 kg (600 mm x 400 mm x 200 mm) and for a starting temperature around -20 \u00b0C \/ -18 \u00b0C.

The maximum microwave power which can be used in processing is limited by the products and not the tunnel. Recipes power vs. time must be chosen according to the compromise between capacity and homogeneity of heating.<\/p>\n\n\n\n

TEMPERING CAPACITY VS. DESIRED FINAL TEMPERATURE<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Example:<\/strong> Chicken \u2243 10.8 t\/h from -18 \u00b0C to -5 \u00b0C or \u2243 6.8 t\/h from -18 \u00b0C to -3 \u00b0C.
Example:<\/strong> Fatty pork \u2243 12.7 t\/h from -18 \u00b0C to -5 \u00b0C or \u2243 9 t\/h from -18 \u00b0C to -3 \u00b0C.

The starting temperature at -20 \u00b0C or -18 \u00b0C has almost no effect on the tunnel capacity if temperature is homogeneous in the whole product.<\/p>\n\n\n\n

TEMPERING CAPACITY VS. PRODUCT TYPE<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Example:<\/strong> butter (10.2 t\/h at -3\u00b0C) or beef 60 % lean (7 t\/h at -3\u00b0C) for the same final temperature.<\/p>\n\n\n\n

TEMPERING CAPACITY VS. FAT CONTENT<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Example:<\/strong> capacity \u2243 7 t\/h for beef 60 % lean, or \u2243 5.2 t\/h for beef 100 % lean from -18 \u00b0C to -3 \u00b0C<\/p>\n\n\n\n

CONCLUSION<\/h2>\n\n\n\n

Capacity is highly variable if final temperature is -7 \u00b0C or -3 \u00b0C, or if meat is lean beef or fat pork. Such variations are linked to physical laws such as for example, latent heat of fusion. Capacity varies according to the processed product (lean beef, pork\u2026), its fat content and the final required temperature.

All the above charts are calculated for a TMW225 operating under following conditions:
\u2022 Power of microwave generator at 180 kW
\u2022 Ton\/Toff at 95 %
\u2022 Blocks or products with regular mass and shape
\u2022 Blocks or products regularly placed on the belt
\u2022 Starting temperature between -20 \u00b0C and -18 \u00b0C homogeneous in all the blocks or products<\/p>\n\n\n\n
