INFORMATION ABOUT DRY AGEING

Meat from animals should not be consumed when the animal has just been slaughtered because of the rigor mortis process that happens to all animal carcasses. Freshly slaughtered meat is tough and fibrous, so it is left to rest while the muscles relax and the piece becomes more tender and its flavour improves. Dry ageing allows this process to happen in a controlled way to obtain juicy meat with optimum flavour and texture.

Your new cabinet performs this meat ageing process by the dry ageing method, which essentially consists of the following:

The pieces of meat must undergo an ageing process for at least 14 to 28 days, but we recommend 21 days. It must never be more than 40 days because, after around day 30, more than 90% of possible muscle fiber breakdown has already happened. Following this period, the softening of the meat is due to decomposition of other proteins, and aroma and flavour are lost. This process should take place in a controlled environment at a temperature close to the meat’s freezing point, but without reaching it (1 to 3°C) to achieve the correct enzyme action. The cabinet should keep humidity stable to control microbial metabolism at around 55%-70% RH. Air flow around the pieces of meat should be constant to encourage ageing and avoid bacterial growth and foul odours enveloping the product. All this results in a process called “proteolysis,” which is the degradation of muscle proteins due to the activation of certain endogenous enzymes. This process enhances the meat’s most flavorful components and amino acids, resulting in meat that is more tender, due to the breakdown of muscle fibres, and juicier. The dry ageing of meat should always be controlled and supervised by an expert responsible for changing the factory settings based on experience. To achieve optimum results, it is essential to understand the process well and use high-quality meat.

Professional supervision of the whole process is essential: knowing the origin and quality of the meat to be matured, mastering the cutting and positioning of each piece, and labelling each piece correctly.

Once the meat has completed its ageing time, the dark and dry parts of the joint must be removed.

The table shows the minimum and optimum ageing times for each commercial category of beef.

Times may vary depending on the animal’s genetics, sex and fat.

GENERAL FEATURES

These appliances have been built to comply with EU food processing and preservation directives.

The cabinet you have purchased creates ideal conditions for the meat dry ageing process. It is available in cabinet format and in various sizes. It has a digital electronic controller that maintains the temperature and relative humidity within the required ranges, and a continuous air circulation system with an external air exchanger system to renew the inside air, equipped with an active carbon filter. It also has an optional automatic UV-C light to eliminate germs and bacteria for purer tasting meat.

The cabinets monitor the higher temperature and relative humidity given off by fresh meat when it is put inside and bring the levels down to the set limit. However, these appliances cannot increase the humidity because they are not equipped with a humidifier.

Only qualified meat control personnel should use this appliance. We recommend carefully monitoring the process during the first few runs to achieve a correct adjustment between the appliance’s working process, location, meat type and the ageing desired by the user.

Remember that dry ageing is recommended only for high-quality cuts of meat, as the process requires meat with a high degree of uniformly distributed fat. Also, bear in mind that the weight of the final product can be between 20% and 30% lower due to moisture loss and final trimming and cleaning before consumption.

The following table specifies the features of each model:

PRODUCT DATA

All appliances have a data plate on one side that identifies the model and shows its technical characteristics. Never remove the plate from the appliance. Example data on the data plate affixed to the cabinet.

Note: This plate is only an example.

Give these characteristics when contacting Technical Service.

INSTALLATION INSTRUCTIONS

 Positioning, installation, repairs and modifications must only be carried out by an AUTHORISED TECHNICIAN, in accordance with the regulations in force in each country.

Improper installation, adjustment, servicing or maintenance of the appliance or tampering with it may result in material damage or injury.

Unpacking

Unpack the appliance and check that it has not been damaged in transit. If it is, notify your supplier and the carrier immediately. If you are unsure, do not use the appliance until the extent of the damage has been checked.

 Packaging materials (such as plastics, expanded polyurethane, and staples) are potentially dangerous, so keep them out of the reach of children.

Do not lay the appliance on its side. If it has been laid on its side, consult the manufacturer about how to proceed. If this happens, after standing it upright, wait at least 2 hours before turning it on. Only maneuver the appliance using a forklift or similar device to avoid damaging its structure. Transport the appliance to the place where you intend to install it before unpacking.
The packaging materials are fully recyclable; dispose of them in the appropriate container.

Positioning and levelling

Keep the area around the appliance clear and clean to prevent the refrigeration unit fan from drawing in any materials that could become deposited on the condenser fins, reducing the system’s efficiency. Remove the pallet, taking care not to knock the cabinet. You can now level the appliance by screwing each of the feet up or down. When it is level, remove the protective film from the stainless steel using a blunt tool. Do not use a knife that could scratch the metal

USEFUL TIPS

Read the following useful tips carefully to get the most out of your appliance.

Carry out the appropriate cleaning operations to ensure a long service life for your appliance.

• We recommend cleaning it before turning it on the first time. Repeat frequently to prevent infection. DO NOT use abrasive, corrosive, acidic, chlorine-based detergents, solvents or gasoline derivatives to disinfect or clean inside the unit.
• If salt blocks are included, unpack them by removing the film, and place them in the steel tray at the bottom of the unit. Check them every 2-3 days to avoid fluid build-up.
• The meat to be matured must be fresh, no more than five days after slaughter.
• To age meat cuts on the grills, make sure they have a good fat cover and around the bone as much as possible.
• Anyone touching the meat should wear protective gloves: no one should touch meat without gloves.
• Clean the appliance periodically and whenever there has been any spillage or there are residues. Before performing any cleaning operation, unplug the unit from the mains supply. These units are fitted with an emergency drain to facilitate cleaning. Either connect it to a waste water drain through a trap or drain it into a tank that is emptied periodically. During cleaning operations, you must remove the plug and clean the drain to avoid clogging it with solids. It is important not to leave any liquid residues that could stagnate.
• Do not clean the appliance with pressurized water jets.
• Condenser cleanness: When cleaning, take care not to bend the condenser’s aluminium fins. If they become bent, the air will not pass through them and condense, seriously damaging the unit. The guarantee will then not cover the necessary repairs.
• Some components around the condenser unit can get very hot, so there is a burn hazard: take the necessary precautions before accessing it. Check that the doors close properly.
• We recommend contacting technical service twice a year to carry out the necessary checks and maintenance.
• If you leave the appliance out of use for prolonged periods (such as holidays or temporary shutdowns), follow these guidelines:
  • Unplug the unit from the mains supply.
  • Empty the appliance and clean it thoroughly.
  • Leave the door ajar to allow air to circulate and prevent mould growth.
