Selecting and Purchasing Used Food Processing Equipment
Used equipment can be a valuable time and cost saving alternative for food and agricultural
product processing. Used equipment costs a fraction of the price of new equipment
and is normally shipped immediately. Multiple pieces of equipment, or even an entire
process line, can be obtained from a single source. This can reduce start-up and troubleshooting
efforts, as well as shipping costs. While many pitfalls exist for the used process
equipment buyer, the advantages can be worthwhile.
The first step in obtaining used equipment is to identify and assess the source or sources. Deal only with reputable suppliers and equipment owners. Ask for references and check them. Sources of used processing equipment generally fall into three categories:
- Dealers (local and national)
Local used equipment dealers are best identified by searching the area telephone book, or business directory, and by word-of-mouth. Classified advertisements in trade journals are a good source to find used equipment dealers and auction announcements. A partial list of national, used-equipment dealers is provided in Table 1. The listing is not an endorsement of any particular dealer or organization. A new variety of Internet-based, used-equipment sources is becoming very popular. Internet sources generally provide a place for posting and viewing equipment information and serve as an interface between the equipment owner and the end customer. Some may feature on-line auctions. Most of these Web sites are searchable and have features that will alert potential customers with email when certain equipment is posted to the site. Table 2 provides a partial listing of Internet-based, used-equipment Web sites.

Often the equipment owner liquidates machinery directly through an auction or other
type of advertised sale. This can be an ideal avenue to acquire a complete processing
line or pieces of equipment with a known history. It can also represent a cost savings
since a purchase from the owner eliminates any re-seller’s profit. Unfortunately,
there is no known reliable method of identifying owner liquidation sales for a particular
type or model of equipment on a timely basis. The advent of the Internet auction may
make this avenue of equipment acquisition more accessible in the future.
Quotations for used process equipment can be solicited by telephone, fax or in person.
The purchaser should consider drafting a request for a quotation before any efforts
are made to obtain quotations. Drafting a request for a quotation will help the purchaser
solidify his needs on paper and facilitate subsequent discussions with vendors. Faxing
requests for quotations to appropriate equipment dealers has proven to be an inexpensive
and effective means of identifying used processing equipment. Visiting a used equipment
dealer has enormous value. Often, a first-hand inspection of equipment stockpiles
will identify appealing alternatives that would have otherwise been missed. When multiple
pieces of equipment can be identified at a single source, a quantity discount may
be negotiated. For additional information on the selection and purchasing process,
please see OSU Fact Sheet FAPC-102, Selecting and Purchasing Food Processing Equipment.
Evaluation of equipment alternatives can be complicated, especially when several people
are involved and opinions differ. The process can be streamlined by using a qualitative
method of evaluation. Key features of the equipment to be evaluated (such as price,
capacity and delivery) can be listed and assigned a weight, or importance, relative
to other features when considering the needs of the specific project. The numerical
weights are assigned according to a convenient, arbitrary scale such as 0 to 10. After
the bids are received, the selected features are rated and given individual scores
for each bid. Again, these scores are based on an arbitrary numerical scale. If the
equipment is to be selected by a committee, the scores can be voted on or averaged.
The total score for each quotation is obtained by multiplying the feature weight by
its score and summing the results. The bid with the highest score is selected for
Maintenance and operation are two features of used equipment that merit extra examination.
Will it be possible to effectively maintain and operate the selected equipment?
Spare parts must be readily available. The original equipment manufacturer may no
longer support obsolete models or components. For example, maintenance technicians
experienced with pneumatic controls are scarce. Can the machine be retrofitted with
digital controls, or can parts and service be obtained from other sources?
Inspection is a crucial step in the used-equipment selection process. A seller will rarely list the undesirable features of an item for sale, so the buyer must learn to investigate. Assistance from an experienced mechanic or engineer can be helpful in this area. Ask for an operator’s manual and/or a maintenance logbook for the equipment. The existence of a maintenance log is a good indication that the machine was well taken care of. Obtain the serial number of the equipment and telephone the manufacturer to inquire about the first owner and intended use of the equipment. Table 3 lists some important inspection areas and examination tips for equipment inspection.
Table 3. Inspection areas and examination tips for used equipment.
|Appearance||All||Is the machine generally well cared for or does it have the appearance of makeshift maintenance? Are the components (if separate) marked and carefully packaged?|
|Log book||The existence of a logbook is a good indication of a maintenance program.|
|Drive-train||Chains, sprockets, belts, sheaves, gearbox||Examine for stretched chains, worn drive belts and sheaves, stripped sprockets and gearboxes. Some problems can be identified when turning shafts by hand (if possible). Listening with the use of a probe (operating machinery) may also help.|
|Rotating shafts||Joints, alignment, key||Look for burrs, warped or bent shafts and cracks. Shafts should not wife when pulled by hand.|
|Bearings||Roller, sleeve||Examine quantity and condition of grease, oil, seals and mounting. Hint: remove grease zerts to inspect.|
|Lubrication||Oil, grease, filters, fittings||Examine for contaminants. Water will turn some oils milky white. Grittiness can sometimes be felt. Samples can be obtained and checked by a laboratory. Check filters.|
|Coatings||Paint, epoxy, tin, Teflon, chrome, rust and scale||Look for chips, flakes and scratches. Beware of fresh coatings that hide defects. Rust can sometimes be removed to reveal very little damage.|
|Welds||All||Smooth and crack-free, no slag or weld splatter present.|
|Operation (capacity)||Operate machine and test for rated capacity. Usually this operation must be arranged in advance with the equipment owner and requires processing materials and complete hookup of the equipment|
|Operation (noise)||Use a listening aid if necessary. Listen for thumps, grinding or unusual sounds.|
|Mating surfaces||Gasket||Surfaces should be smooth. Gaskets will be intact and flexible.|
|Controls||Panel, switches, pushbuttons, displays, timers, alarms, outputs, interface, charts||Examine condition and operation of all components. Wiring in electrical box should be labeled and correspond to a posted or available diagram. Displays should be clear, not fogged or waterlogged|
|Utility connections||Electric, steam, water, air, gas, hydraulics, chilled water, sewage and other||Determine capacities, such as voltage, frequency and flow rate. Examine connections for integrity.|
|Fasteners||Bolts, clamps, pins, screws and snap rings||Examine for missing or damaged components such as threads or head.|
|Safety features||Shrouds, insulation, kill switch, stickers, doors, vents and valves||Look for missing, damaged or disabled components. Stored energy contained in elements such as springs and air cylinders must be properly relieved.|
Safety features are an issue (listed in Table 3) that may require additional attention
when purchasing used equipment. Older equipment may have met safety standards when
first introduced to the market, but may fall short of current standards. Safety features
on used equipment may be disabled or missing. Issues pertaining to safety must be
resolved before the machine is put into operation for legal and moral reasons. The
cost to upgrade equipment to meet current standards may be prohibitive.
Purchasing and installing used equipment may be the best alternative for a cost effective process installation. It can also be an exciting and potentially dangerous adventure. Research and investigation before purchasing will help improve the chances of success.
