Food deprived of the use of vacuum packaging machine vacuum after which an advantage to exclude part of the packaging container of air (oxygen), can effectively prevent food spoilage. 2, the use of barrier (tightness) excellent packaging materials and sealing technology and strict requirements, can effectively prevent the exchange of substances in the package contents can be avoided by food weight loss, loss of taste, but also to prevent secondary pollution. 3, vacuum-packed container internal gas has been ruled out, accelerated heat conduction, which can improve the efficiency of heat sterilization, but also to avoid the heat sterilization, due to expansion of the gas leaving the container rupture. In the food industry, vacuum packaging applications is very common, a variety of cooked products such as chicken, ham, sausage, grilled fish, beef jerky, etc.; various pickles and pickled products such as soy products, dried fruit and other kinds of fresh food needs increasing use of vacuum packaging. After vacuum-packed food preservation and long, greatly extend the shelf life of food.

When you reach a certain degree of vacuum, into sealing procedures 7. Sealing After entering the cooling state, and then deflated, packaging completed 8. put the vacuum chamber Cover pressed to another vacuum chamber to begin another cycle Troubleshooting: a degree of vacuum is low: pump oil pollution, too little or too thin vacuum cleaning, replacement of vacuum pump oil. Extraction time is too short to extend the extraction time. Suction filter is clogged exhaust filter cleaning or replacement. There is leakage Department, was evacuated off the power and check the solenoid valve, fittings, vacuum suction valve and seal air leaks around the studio office. Second, without heating: heating strip blown, replace the heating strip. Heating time relay burn (the boot that two lights lit simultaneously, OMRON light color is yellow), the replacement time relay. Plus hotline blown, replace the heater wire and securely installed. Control the heating temperature band switch is bad, repair or replacement. AC contactor controlled heating is not reset, repair (with airflow blow foreign body) or replaced. Heating transformer is bad change. Third, the heating does not stop: the heating time relay is bad or burn, adjust the time relay with socket contacts or replacement. AC contactor controlled heating is not reset, repair or replace the four, sealing uneven, not tight or do not seal: heating time and heating temperature is not adjusted, adjusted to fit. Heating cloth with attachments, gently scrape off with a fingernail attachments. Pressurizing solenoid valve does not clean or replace the solenoid valve. Replace damaged airbag airbag. Pressurized pipe breakage, repair or replacement. Hold the gas cooling time relay bad (electrical box) replacement time relays. Release valve circuit breaker, find and connect. Release valve stuck or burnt, remove the cleaning or replacement. Five, noise: Replace worn or broken pump coupling. Exhaust filter clogged or installation location is not correct, clean or replace the exhaust filter and installed correctly. A leak at the check valve for leaks and ruled out. Six, injector pump: suction valve O-ring off, unplug the pump suction nozzle mouth of the tube remove, remove the suction valve spring and gently stretch the O-ring several times, reinsert it into the recess tank, and then install it. Rotary vane wear, replace the rotary vane. Seven, vacuum pump oil: oil return valve plug, remove the oil return valve, cleaning (see instructions). Oil window loose, put the oil, remove the oil window, wrap Teflon tape or thin plastic film. Eight, vacuum hood Large: suction filter is clogged or dirty exhaust filter cleaning or replacement. Replaced with new oil pump oil pollution. Return valve plug, clean the oil return valve (see instructions). Nine, while heating, while not heating: unheated side of the bag with the heating device layering short (generally associated with copper lug short) position adjustment brazing sheet, or break packaging pocketed layering. Ten, vacuum pump will not turn: studio not Gaiyan will Gaiyan studio. Motor reversal (re-adjust the wiring); eleven, closing lid does not work: there is no power, check whether the power supply. Limit switch is not operating, adjust the limit switch paddles; twelve, frequent burning Insurance: a short-circuit at, find and eliminate. Motor reversal time is too long, swap any two-phase power line installation (except ground). Oil viscosity is too high, cleaning pump and replaced. Service: a user after purchase instructions must be strictly detailed look before proceeding. During the warranty period the user does not press the manual for the correct operation of the use, maintenance, maintenance or unauthorized removable parts warranty does not cover damage caused by the column, but the company still be repaired at the expense of the users themselves. Second, the warranty period: one year warranty mechanical parts, electrical components warranty for six months. (Except consumables) three charges: the device over the warranty period according to customer requirements provide on-site services specified by the Company: a charge three hundred yuan Shanghai area home repair services, spare parts costs surcharge. (Sent to the Company's stand-alone charge maintenance fees 100 yuan) two other domestic provinces and municipalities according to customer requirements to provide home repair services by 500 yuan / person / day billing, plus round-trip fare, accessories charged separately. Four, Payment: cash or check now end. Fifth, the company reserves the final interpretation.
