Cheese-Making Technology
Success with ALPMA
2
The many different varieties of cheese which are typical of a country or a region, with their countless subtle varia-tions in taste, present a great challenge to ALPMA.Our specialists know which technology to use in order to maintain the unique charac-ter of each regional speciality. At the same time, they ensure that the quality remains at the highest possible level.
A worldwide taste.
Or is a new type of cheese perhaps to be developed instead of a traditional cheese?
With our long experience of cheese production all over the world, we are the right partner for you. The new product would combine the qualities of a long shelf life, appearance
and packaging with those characteristic qualities peculiar to a specific region. Of course, local preferences play an important role in developing this new taste.

It’s the milk that counts.
Milk is a valuable natural foodstuff. Working with it requires great diligence. Our treatment of milk, which prepares fat and protein content for the cheese-mak-ing process, is based on inter-nationally recognised hygiene guidelines. Consistent high quality is an essential prerequisite for optimal control of production.
Regardless of whether 10,000 or a million litres a day are processed – without an intel-ligent automation concept it is not possible to achieve this in an economically efficient manner. That’s why we can supply the following:

Regardless if it is a continous process or a batch-process – cheese production is an extremely delicate business.
After the addition of the culture and rennet to the milk, a very important phase begins. Every single vibration could now affect the success of the process. The sophisticated technique of the Coagulator ensures a vibration-free coagulation zone. The curd coagulates in a compartment built by the belt and the spacing plates. The belt smoothly slides through the Coagualtor-vat on a fine film of water. The delicate coagulum it bears is precisely cut and gently, but intensively processed, sur-passing the manual skills of even the best cheese maker.
Everything is arranged for a precise and continuous pro-duction process in order to maintain a consistently high level of quality, whilst re-ducing losses to a minimum.
Continuous production is the key to the optimisation of the production processes.

Still the ALPMA Coagulator 2000 is the only fully continuously working curd preparation unit available on the market. Since the start-up of the first Coagulator unit in 1975 this system has constantly been improved. It provides high production reliability, while it is easily and quickly adjusted to the next cheese type.

Correct whey drainage means neither too much nor too little.
The quantity of the remaining whey at the filler is an impor-tant factor in determining the type of cheese to be produced. Using the whey drainage drum and filter belts, this process can be exactly controlled. Whether set up as an individual unit or arranged in a line, they prepare the curd perfectly for the filling process.The machines are designed to the highest hygiene standards and are regularly cleaned during the production processes.
You too can profit of maximum yield!

Curd filling is precise work.
The quality of the cheese is influenced very early in the production process by the qual-ity of the curd and the filling technique. Mistakes made here cannot be corrected later. We therefore pay close attention to the process steps at these stages.
Continuous curd supply is a basic requirement for exact and precise filling in order to ensure perfect quality. The filling procedures in turn affect weight, consistency, form and quality of the final cheese product.
ALPMA has developed a whole family of filling devices in order to meet demands required by the various types of cheese. Consequently, it is possible to define the right technology for every type of cheese.
Every portion’s a hit.
The semi-automatic filling device permits
exact dosage, accurate hygienic filling and
accurate control of the draining whey without significant loss of curd.
Extremely soft varieties of curd with a large grain size are placed gently in the moulds, layer by layer, by means of immersion filling.
Large Feta-blocks can be filled automatically

maintaining a high standard of performance
and a high capacity.

If the edges of your yellow cheeses should be tight and smooth. If curd texture should be regular. If only typical gas holes may be visible at the cut surface. If the filling device for curd and whey should be as small and com-pact as possible. If it should be easy to clean. If filling should be exact and repro-ducible.
Then the award-winning technique of ALPMA’s FORMATIC-filler will redound to optimum results.

Function follows Form.
Blockforms have a great deal of influence on the shape, dry matter content and final weight of the cheese. There-fore, the mould development programme at ALPMA is par-ticularly important.
Moulds can come in many shapes and sizes, but they are always unique.

Extensive on-site testing is usually the only way to find the right mould. The arrange-ment and drainage properties of the holes and grooves are often decisive. Tenths of milli-metres can be critical here!
The use of genuine food-grade synthetic materials permits a full range of design options, from the improvement of traditional moulds into mar-keting-compatible appli-cations with company logos.

Moulds can come in many shapes and sizes, but they are always unique.
The special construction of the ALPMA Blockforms is a major factor in preventing whey drained from the upper cheeses from dripping onto the lower ones during the drainage phase. The Blockforms are easily stacked. Thanks to spe-cial centring pins, even high stacks remain extremely stable.
The bases of the moulds are structured so that they are identical on both upper and lower surfaces. This means that when the cheese is turned, the mould retains the same drainage characteristics. By stacking of the Blockforms a chimney-effect is achieved by which a constant climatisa-tion takes place inside the stack. As the curd is in direct
contact with the mould for a long time, this brings particu-lar challenges to meeting the highest standards of hygiene and also the cleaning pro-cesses of the moulds. The plastic materials chosen for the moulds meets all the guidelines set down by the American FDA.

Your cheese is happy here.
The ALPMA climate-control conveyor systems offer the best chance to control the specific drainage characteris-tics of each cheese type. The development of the cheese rind and the growth of bacte-ria are best influenced by means of warming, steaming or by cooling. The combination of the fans help the chimney-effect of the stacked Block-forms to offer unrivalled, even drainage of the cheese. This has the very positive effect of reducing variations in the cheese weights to a minimum.

Storage space is valuable and expensive.
Consequently, one should make the best use of what’s available – stack the racks high! The ALPMA Stacker can utilise space so well that Block-forms, turning sheets, turning plates and racks are precisely stacked together without the risk of falling. The parts can be lifted directly from the floor or taken off the conveyor system.Many cheese-making plants already make use of well-proven belt stackers. For places where room is restricted we have developed a special

Time to think about turning.
Stack turners or single turners are, depending on the tech-nology and involved mould materials, effective solutions to support drainage and shaping of the cheeses. As a rule, trays are placed in the single turner. They can also be stacked and turned. Blockforms are only turned as a stack. The turning pro-cess is programmable so that the required shape and sur-face characteristics are achieved.
We tailor our solutions to your company size and capacity.
The turning device is capable of turning cheese moulds with plateau-system and
racks as well as empty Block-forms, e.g. for cleaning.

Salt not only adds taste, it also protects the surface of the cheeses.
Brine bath and dry salting units have proved essential methods in fulfilling the special requirements of each local variation.As well as being a useful means of salting cheese, brine baths offer a means of control-ling the cheese temperature and the culturing of the bacte-ria, thus influencing the final taste.

Those who operate large brining units know just how important it is to have an efficient flow. The coordina-tion of the loading and unloading, as well as the length of time the cheese is in the bath and the overall space requirements are expensive and require detailed planning.The dry salting machine is particularly suitable for com-pact shapes and requires very little space.

The suction heads remove the cheeses from the Block-forms gently and reliably and place them carefully on to the racks. The empty Blockforms are then taken to the cleaning unit.
Everybody needs to get out some time.
And you want this to happen quickly and gently. The load-ing of the maturing racks is carried out by means of a vacuum demoulding unit.The vacuum used to with-draw the cheese from the Blockforms is very small, and does not damage the delicate skin of the raw cheese. The suction devices are con-
structed according to the highest hygiene standards and are simple to clean.

Cheese needs peace to mature.
Continuity is also important during the maturing process. The cheese can only ripen to its desired delicate flavour when it is matured in consist-ent climatic conditions, with the corresponding tempera-ture, humidity and air circula-tion. The highest standards of hygiene are essential if the maturing process is not to be disturbed. For this reason, manual operations should be avoided. Mechanised maturing room processes in combination with climate-control equip-ment offer the best possible conditions.The disturbance that can occur during transport to other levels can be avoided by use of the multi-storey lift.
Leave nothing to chance!
While saving space and with no exchange of air, the cheese stacks are raised via the multi-storey lift to the maturing room.
