SECTION 1 - INTRODUCTION

1 INTRODUCTION

1.1 Overview of EquipmentThe Meiko AZP 80 is a commercial wastepulper intended for processing food wasteand mixed kitchen waste. The applianceconsists of a grinder and a water separator ina close-coupled formation inside a commonhousing.Waste is fed into the machine using either amanual feeding opening, or by an optionalwater trough. Waste is moved through themachine by the flow of water controlled byan internal recirculating pump that minimizesthe need for additional water. For unitsequipped with a feeding trough, the machine’sinternal recirculating pump also provides awater supply for the trough system.Waste is drawn into the grinding wheel bywater flow. The grinder consists of a powerful8.8 hp/6.6 kW motor, grinding disk, filter ringand knife. Cutting teeth are made fromtungsten carbide for superior performanceand longer life. After the waste is ground intoa pulped mass, sieve openings in the grinderwall allow it to be drawn through and guidedto the water separator.

The separator consists of a perforatedcylinder and a screw. As the screw rotatesinside the cylinder, the ground waste ispressed against the perforations, whichremoves water from the waste, compacts it,and lifts it. Separated water escapes throughthe perforations in the cylinder, drains downward,and is returned to the grinding tank. The solid,nearly-dry pulp is routed out of the top of themachine by a waste chute, which can beemptied into a normal, lined garbage can foreasy disposal. A volume reduction of up to85% is possible using the AZP 80 with normalkitchen waste. A 70% reduction is typical.For efficient and SAFE operation, be sure tofollow the installation and operatinginstructions provided in this manual. Inparticular, all safety symbols and notices onthe equipment and in the supplied docu-mentation must be followed.IMPORTANTMeiko waste pulpers have been designedexclusively for the pulping/dewatering of foodand mixed kitchen waste in a commercial orinstitutional setting according to theguidelines in this Manual and must not beused for any other purpose.

3.8 Water Supply Connections

CAUTIONBefore connecting the water supply lines, theyMUST be flushed clean of all debris, including(but not limited to) pipe sealant, metalparticles, solder, etc. This debris can damagethe appliance.IMPORTANTIn some cases, local codes dictate that watersupply connections be made only by acertified professional.The water supply connections for the wastepulper are located behind an access panelon the front of the machine. Both connectionsare 3/4” male NPT. See Figures 3-3 and 3-5.1. Check that iron or other metal particles

cannot contaminate the fresh watersupplied to the dishwasher.

2. Check the incoming water temperature.• The dual valve connection, located

closest to the front of the machine, isused for the recirculating water supply,and should use cold water (50°F/10°Crecommended).

• The single valve connection, locatedbehind the dual valve connection, isused as a warm water rinse for thedewatering press. It should use warmwater (110-140°F/42-60°C).

3. Check the incoming water hardness.Meiko recommends a hardness of 4-6grains per U.S. gallon for proper operationand to minimize lime scale buildup.

4. Because the water inlets incorporate dirttraps, additional traps are unnecessaryunless required by local, national orinternational codes.

5. Connect the customer-supplied waterline(s) to the appropriate connection(s).

areas), food waste (prep areas)• Inorganic materials - Small plastics and

polystyrenes (plastic utensils, Styrofoamcups), cardboard, etc.

The following materials should NOT be fedinto the machine:• Metal• Glass• Porcelain and china• Large bones• Plastic bags• Oils and grease

Waste can be loaded into the machine usingeither the manual feeding opening or anexternal recirculating feeding trough (if soequipped).

External feedingtrough (typical)

Manual feedingopening

For the most efficient operation:• Load the waste steadily, instead of in large

batches or “piles.”• Waste should be mixed, instead of sorted,

when loading the machine.• Any containers (cups, etc.) loaded into the

machine should be opened and loadedempty. Any remaining waste inside themshould be emptied into the machine first.

• Any floating waste (Styrofoam, etc.) willtake longer to grind and process, reducingthe efficiency of the machine.

• Some waste, particularly products thathave a high grease or oil content, mayproduce a foaming effect in the tank. Otherwastes may accumulate on the cuttingwheel. Both of these conditions will reducethe efficiency of the machine.To reduce foaming and wasteaccumulation on the cutting wheel:- Mix foaming wastes with other, more

absorbent wastes (cardboard plates,etc.)

- Add a foam-absorbing product (paperor cardboard shreds, etc.) to the wastemix.

Load the waste into the machine steadily,instead of in large batches or “piles.”

4.4 Idle PeriodsDuring idle periods,press the STOPOPERATION button. Themachine will enter a 15-minute self-cleaningmode to flush debrisfrom the dewateringpress tower, and thenshut off the grinder,separator andrecirculating pump.
