DM-350B floor type map tray sealing equipment (tray sealers food packaging) features high degree of automation, reliable quality, long service life, high yield and wide applicability.
According to different fresh-keeping gases required by the food, there are three choices for user: mixing ratio combining of three fresh-keeping gases, two fresh-keeping gases and one fresh-keeping gas
The DM-350B Tray Sealers Food Packaging can make high-precision adjustment for the required fresh-keeping gas and mixing proportion according to different food types to make the food fresh-keeping achieve the best state.


DM-350B floor type map tray sealing equipment can be used for fresh-keeping packing of different types of fresh and cooked food. The type and mixing proportion of fresh keeping gas are different for different types according to the food’s characteristics.

Technical Characters

1. Control System: OMRON PLC programmable control system
.The data setting and motion control are more accurate and the performance is more reliable, so the operation is easier.

2. Electric System: France Schneider electric elements is equipped with long service life and high applicability to assure reliable quality of the floor type map tray sealing equipment.

3. Pneumatic System: SMC pneumatic elements.
Long service life and high applicability leads to reliable quality. Equipment failures can be effectively avoided to allow the continuous use without being interrupted by quality matters.

4. Structure Material: Regarding to the main structure material, the floor type map tray sealing equipment adopts 304 Stainless Steel, which is safe and easy to clean.
5. Gas detection method: precise gas detection means.
Germany WITT gas analyzer is used for testing the gas within the food packing period to ensure that the tray sealers food packaging reach the specified precision.

6. Vacuum System: Germany BUSCH vacuum pump (high oxygen vacuum pump) is equipped with high vacuum degree and long service life to assure reliable quality.

7. The Germany WITT gas mixer adopts real-time gas mixing, which accuracy is higher than ± 1%. The quality of food packing of each box is guaranteed to be always consistent. The quality and preservation period of the packed food are controlled effectively.

8. Gas displacement system:
The totally enclosed vacuum chamber gas replacement technology is used to guarantee the high replacement rate (replacement rate ≥ 99%).
9. Work status indication:
The floor type map tray sealing equipment has an operating program status and failure real-time display function to monitor the equipment to ensure the normal operation of the machine.
10. Gas displacement system can minimize the residual oxygen content within the packing pallet and effectively guarantee the mixing precision of the mixed gas within the food packing pallet.
11. User can effectively control the storage, logistics and sales time of the fresh keeping food, and prolong the shelf life accordingly.
12. Easily replaceable of sealing mould: Different size of the trays is available according to different requirement.

13. Heavy duty casters: Universal caster wheels with brake function are mounted at the bottom of the floor type map tray sealing equipment for user to move and fix the machine.

14. Safety start button: The security measures of the machine only can be started by simultaneous operation of both hands, which effectively prevents security incidents caused by malfunction of the operator.

15. Emergency stop switch: Tray sealers food packaging is equipped with an emergency stop switch which can be pressed in case of abnormal condition to terminate all ongoing work programs and guarantee the safety of equipment and personnel.
