Pet Food Case Study

A​ ​Pet​ ​Food​ ​Company​ ​Upgrades​ ​to​ ​APEC's Mistcoater

Here’s​ ​why​ ​a​ ​pet​ ​food​ ​company​ ​decided​ ​to​ ​upgrade​ ​from​ ​a​ ​tumble​ ​drum​ ​coater​ ​to​ ​APEC's Mistcoater​ ​Liquid​ ​Applicator,​ ​and​ ​the​ ​successful​ ​outcome​ ​of​ ​making​ ​the​ ​change.

The​ ​Issues

To​ ​apply​ ​both​ ​fat​ ​and​ ​flavors​ ​to​ ​their​ ​pet​ ​food,​ ​our​ ​pet​ ​food​ ​client​ ​had​ ​been​ ​using​ ​a​ ​traditional tumble​ ​drum​ ​coater​ ​for​ ​many​ ​years.​ ​However,​ ​this​ ​equipment​ ​simply​ ​wasn’t​ ​up​ ​for​ ​the​ ​task​ ​and also​ ​posed​ ​a​ ​few​ ​safety​ ​risks.

Because​ ​of​ ​the​ ​way​ ​tumble​ ​drum​ ​coaters​ ​work,​ ​suspended​ ​solids​ ​clogged​ ​the​ ​spray​ ​nozzles. This​ ​caused​ ​poor​ ​uniformity​ ​of​ ​coatings.​ ​Also,​ ​due​ ​to​ ​the​ ​excessive​ ​backpressure,​ ​premature failure​ ​of​ ​pumps​ ​and​ ​valves​ ​were​ ​a​ ​common​ ​occurrence.​ ​To​ ​remedy​ ​this​ ​problem,​ ​the​ ​nozzles needed​ ​to​ ​be​ ​cleaned​ ​and​ ​serviced​ ​often.

As​ ​far​ ​as​ ​safety​ ​went,​ ​the​ ​open-ended​ ​drums​ ​created​ ​a​ ​slipping​ ​hazard​ ​from​ ​the​ ​escaped atomized​ ​liquid.​ ​Constant​ ​cleanup​ ​of​ ​the​ ​surrounding​ ​area​ ​was​ ​needed.​ ​When​ ​it​ ​came​ ​to cleaning​ ​the​ ​inside​ ​of​ ​the​ ​drum,​ ​its​ ​excessive​ ​length​ ​and​ ​lack​ ​of​ ​easy​ ​access​ ​meant​ ​a​ ​person needed​ ​to​ ​actually​ ​go​ ​inside​ ​the​ ​drum​ ​to​ ​be​ ​able​ ​to​ ​properly​ ​clean​ ​it.​ ​This​ ​practice​ ​can​ ​quickly turn​ ​into​ ​a​ ​dangerous​ ​situation.

Dealing​ ​with​ ​these​ ​serious​ ​issues​ ​resulted​ ​in​ ​high​ ​labor​ ​costs,​ ​too​ ​much​ ​down​ ​time​ ​on​ ​the​ ​line, and​ ​the​ ​potential​ ​for​ ​a​ ​work-related​ ​accident.

The​ ​Upgrade

When​ ​this​ ​company​ ​decided​ ​it​ ​was​ ​time​ ​for​ ​an​ ​upgrade,​ ​they​ ​turned​ ​to​ ​​APEC​,​ ​who​ ​has​ ​been providing​ ​innovative​ ​pet​ ​food​ ​processing​ ​solutions​ ​for​ ​over​ ​25​ ​years.

APEC​ ​needed​ ​to​ ​work​ ​within​ ​the​ ​available​ ​footprint​ ​and​ ​provide​ ​a​ ​coating​ ​system​ ​that​ ​eliminated all​ ​of​ ​the​ ​issues​ ​with​ ​tumble​ ​drum​ ​coaters.​ ​The​ ​answer​ ​was​ ​the​ ​Mistcoater​ ​Liquid​ ​Applicator.

Using​ ​spinning​ ​disks​ ​in​ ​a​ ​continuous​ ​flow​ ​process​ ​instead​ ​of​ ​spray​ ​nozzles​ ​prevented​ ​clogged nozzles,​ ​even​ ​when​ ​suspended​ ​solids​ ​were​ ​being​ ​applied.​ ​Since​ ​there​ ​is​ ​no​ ​restriction​ ​on​ ​liquid inlet,​ ​the​ ​backpressure​ ​that​ ​can​ ​cause​ ​excessive​ ​strain​ ​on​ ​pumps​ ​and​ ​valves​ ​is​ ​eliminated.

As​ ​far​ ​as​ ​cleanability​ ​and​ ​safety​ ​goes,​ ​APEC’s​ ​Mistcoater​ ​Liquid​ ​Applicator​ ​is​ ​completely enclosed​ ​so​ ​overspray​ ​no​ ​longer​ ​occurs​ ​in​ ​the​ ​surrounding​ ​area.​ ​To​ ​prevent​ ​buildup​ ​on​ ​the walls​ ​of​ ​the​ ​coating​ ​chamber,​ ​internal​ ​scrapers​ ​are​ ​built​ ​right​ ​in.​ ​When​ ​it​ ​is​ ​time​ ​for​ ​a​ ​full cleaning,​ ​full-length​ ​access​ ​doors​ ​allow​ ​sanitation​ ​to​ ​take​ ​place​ ​without​ ​having​ ​to​ ​climb​ ​inside the​ ​machine.

The​ ​Outcome

The​ ​outcome​ ​of​ ​the​ ​upgrade​ ​has​ ​been​ ​tremendous.​ ​Since​ ​the​ ​fat​ ​and​ ​flavorings​ ​are​ ​now​ ​being atomized​ ​properly,​ ​the​ ​product​ ​coating​ ​uniformity​ ​has​ ​greatly​ ​improved.​ ​This​ ​system​ ​also enables​ ​multiple​ ​liquids​ ​to​ ​be​ ​applied​ ​through​ ​one​ ​inlet​ ​point,​ ​quickening​ ​the​ ​coating​ ​process.

The​ ​down​ ​time​ ​that​ ​was​ ​previously​ ​required​ ​for​ ​maintaining​ ​and​ ​cleaning​ ​the​ ​spray​ ​nozzles​ ​and surrounding​ ​area​ ​is​ ​virtually​ ​eliminated,​ ​as​ ​well​ ​as​ ​the​ ​safety​ ​hazards​ ​of​ ​slipping​ ​on​ ​overspray and​ ​climbing​ ​into​ ​the​ ​drum​ ​for​ ​cleaning.

Due​ ​to​ ​these​ ​exceptional​ ​results,​ ​the​ ​pet​ ​food​ ​client​ ​has​ ​now​ ​replaced​ ​every​ ​single​ ​one​ ​of​ ​their tumble​ ​drum​ ​coaters​ ​with​ ​APEC’s​ ​Mistcoater​ ​Liquid​ ​Applicators,​ ​as​ ​well​ ​as​ ​having​ ​installed​ ​them in​ ​their​ ​brand​ ​new​ ​processing​ ​facility.

APEC​ ​couldn’t​ ​be​ ​more​ ​proud​ ​and​ ​their​ ​pet​ ​food​ ​client​ ​couldn’t​ ​be​ ​more​ ​pleased​ ​with​ ​these results. Contact​ ​APEC​​ ​or​ ​visit​ ​us​ ​online​ ​for​ ​more​ ​information​ ​about​ ​our​ ​​Mistcoater​ ​Liquid​ ​Applicator​!
