Derinding Machines

Sturdy, reliable, proven

The NOCK derinding machines persuade through their perfectderinding results. They operate with an ingenious geometry of thetransport roller, blade holder, pressure device andinfeed conveyor. The blade holder mounting isspring suspended so that the blade holder adjustsoptimally to the thickness of the rind (skin).The pressure roller is spring suspended in allmodels and in most models it is also infinitelyvariable in height. This way all pieces such asbelly of pork, backs of pork, top pieces ofbacon, flat cuts, loins, hams and so on can beflawlessly derinded. Even freshly slaughteredmeat can be easily processed. Bacon slabs canalso be sliced.

The mechanically highly strained machine components such asdrive, transport roller, blade holder and pressure device are moun-ted in solid, 15 mm thick base plates, the NOCK POWER PLATES®,which are located in the machine casing. Thousands of NOCKmachines have since 1990 proven this construction. In comparisonto the mounting of these parts in the casing like known from otherbrands the NOCK construction has deciding advantages:

n Long lasting precisionThe NOCK POWER PLATES® guarantee an excellent bearingalignment and precise positioning of the machine parts.And thereby a constant better function of the machine.

The covers of the NOCK conveyorized machines are constructedsimilar to a tunnel:

All machine parts which could obstruct the flow of the product, forexample the mountings and handles of the blade holder, the moun-tings of the pressure device and of the conveyors, are located outsidethe tunnel-like safety cover.The advantages:

n Reliable product flow ("easy flow")= higher processing safety

n Hardly any accumulation of surpluses on the mountings duringprocessing = better processing hygiene and faster cleaningof the machine

A safety switch stops the machine, once the cover is opened.A safety bolt hinders reliably that the opened safety cover does accidentally fall closed.The NOCK EASY-FLOW® safety cover complies to the European safety standard EN 12355 und bears to the high occupationalsafety of the NOCK derinders.

Interference-free productflow due totunnel-likeprotectionagainstmachine parts

n No material fatigueWhen the highly strained parts of a derindingmachine are positioned on the casing, sooneror later it can come to deformation or crevices. With a 15 mm thickness, the NOCK POWERPLATES® are resistant to material fatigue.This has been proven by thousands of NOCKmachines since 1990 in the hardest industrialoperation, even in several shift operation.They make the NOCK derinders especiallysturdy and durable.

n Service friendlinessAll components are very easily accessibleonce the side covers are opened.

n Hygienic and easy to clean machine surfacesDue to the positioning of the machinecomponents on the NOCK POWER PLATES®,the steel casing can be designed with largesmooth surfaces. This makes the NOCKmachines particularly hygienic and easyto clean.

The NOCK ACTIVE SKIN GRIPPER® (ASG) optionally available forall industrial models offers further important advantages:

n Flawless first cut and perfect derinding also with very thinskinning, hence less trimming

n Noticeable increase of yield and best rind qualityn Longer durability of pressure wheels, as less force is applied to

the product (softer pressure springs)n Relief of the blade due to less contact with the rindn Thus amortization of the extra cost within a short space of time

NOCK is an owner run German family business, which since 1990constructs and and successfully sells modern machines for themeat processing industry worldwide. In close contact to meat processing plants and distributors, the machines are constantlyfurther developed. Of course the latest hygiene and safety standards are respected.

NOCK offers German high class workmanship to interestingprices due to modular construction, modern production methodsand strict cost management. This is an important aspect conside-ring the often tightly calculated investment budgets of meatprocessing plants.

NOCK stands for uncompromising quality “Made in Germany”.This begins with the quality-orientated concept and constructionof the NOCK derinding machines, comprising of themanufacturing of all central components at the company-ownultra-modern machine park, exclusively using premium basematerials and acquired parts, the collaboration with establishedsuppliers, diligent assembling and final inspection of theNOCK machines. An experienced team of highly qualified andmotivated employees also contributes significantly to this highquality standard. This results in modern, particularly reliableand durable machines of continuous quality.

n The NOCK machines have not only a modern, but also ahygienic design, of course complying with the latest hygienicstandards.

n Casing, conveyor frames, transport roller, blade holder and soon are made of high quality stainless steel. The conveyorbelts and pressure wheels are made of approved food safe plastics.

n Due to the standard installed NOCK POWER PLATES®, it ispossible that the machines can be designed with large smoothsurfaces, which are particularly hygienic and easy to clean.

n The NOCK EASY-FLOW®-safety cover prevents a build-up ofproduct surpluses on the mountings of the blade holder and thepressure unit during processing.

n All of the NOCK derinders except the table model Cortex C 420are equipped with lockable castor rollers. This eases thetransporting process to a cleaning area.

for the NOCK derinding machines

Quick and easy to clean:NOCK derinder after removing conveyor, pressure roller andblade holder. Scraper comb tilted back.

Conveyors, pressure roller, blade holder, exchangeable tables andoutput sheets can be removed and replaced for cleaning purposesfrom the machine within seconds without any tools. Thereforesoiled parts are easily accessible. The scraper comb can be tilteddownwards, the transport roller can be turned by hand. The conveyor frames can be folded back so that the inside of the conveyor can be cleaned. The belts can also be easily removed from the frames for thorough cleaning.The machines can be optionally equipped with plastic modular belts.

Quick cleaning andoptimal hygiene

Top quality -Made in Germany

Top operational safety also foropen top machines

The new NOCK IMMEDIATE CUT-OUT ® (ICO) safety system practically eliminates the risk of injuries when working with opentop derinding machines.

Ferdinand Nock, comany founder

The conveyorized NOCK derinding machines for the small tradecan be operated, in addition to automatic conveyorizedoperation also as an open top (manual) machine, to derind forexample round pieces of ham. (Flat pieces must only beprocessed in conveyorized operation according to EN 12355.)

Besides this the machines are equipped with an in the heightadjustable foot switch bar and an infeed table. In comparison tothe industrial types, the slower speed setting simplifies processing on an open top machine.

The adjustment of the machine can take place in secondswithout any tools:Open the NOCK EASY-FLOW® safety cover – remove pressure rollerand place it in the provided notch in the safety cover – removeinfeed conveyor – mount infeed table – done.
