Equipment Introduction:

The brine injection machine is a key piece of equipment in modern meat processing, primarily used in the curing process for products such as Western-style ham, barbecued meats, and marinated meats. It rapidly cures meat by injecting prepared brine, starch, soy protein, and other ingredients into the meat, enhancing flavor, preserving nutrients, and improving taste. This improves meat quality and yield.

Equipment Parameters and Description:

The operating principle of the brine injection machine can be summarized as "simulated injection, high-pressure penetration." Its core process is as follows:

1. Prepare the marinade: First, according to the product recipe, dissolve the marinade ingredients (such as salt, sugar, phosphates, spice extract, starch, etc.) in water to create a uniform marinade, which is then kept at a low temperature (typically 0-4°C).

2. Place the raw meat: Place the entire piece of raw meat to be processed (such as pork hind leg, chicken breast, turkey, ham, etc.) flatly on the machine's conveyor belt or injection platform.

3. Injection Process:

① Needle Plate Lowers: After the machine is started, a plate densely packed with injection needles moves downward under hydraulic or pneumatic pressure, precisely penetrating the raw meat.

② High-pressure Injection: When the needle plate reaches the predetermined position, the valves connected to each injection needle instantly open, and a high-pressure pump (adjustable pressure, typically 0.1-0.8 MPa) forces the marinade into the muscle fibers.

③ Injection needle plate rises: After injection is complete, the needle plate rises, and a conveyor belt removes the injected meat, while a new piece is fed in, starting the next cycle.

④ Special design: The end of the injection needle typically features multiple small holes to ensure that the liquid is evenly distributed, rather than concentrated in a single spot. Furthermore, some high-end equipment features "step-by-step" injection or "massage" functions to ensure that different parts of large pieces of meat are evenly treated.

4. Recovery and filtration: The marinade that seeps or drips from the meat is collected and filtered through a filtration system to remove meat residue and impurities before being returned to the storage tank for recycling, minimizing waste

Explanation:

Number of Injection Needles: Generally, the more needles, the greater the injection coverage per unit time, and thus, the higher the production efficiency. Injection Rate: This refers to the percentage of the weight of the marinade relative to the weight of the raw meat. For example, a 40% injection rate means that 40 kg of marinade is injected into every 100 kg of meat.

Injection Pressure and Effectiveness: The injection pressure can be adjusted between 0.1 and 0.8 MPa, depending on the product. Higher pressure facilitates marinade penetration, but excessive pressure may damage meat tissue.

Equipment Advantages

1. Improved Quality and Yield:

Injection marinating can tenderize and soften the meat, improving the taste and yield of the meat product. This directly enhances both the taste and economic benefits of the product.

2. Significantly Improved Efficiency:

Compared to traditional static marinating, automated injection can significantly shorten marinating time, adapting to the pace of continuous production lines.

3. Flexible and Controllable Process:

Utilizing a variable frequency speed controller, the chain step distance and speed can be adjusted synchronously with the needle injection speed. The injection pressure can be adjusted between 0.1 and 0.8 MPa depending on the product, and the injection rate can also be adjusted to meet different product and process requirements.

4. Safe and hygienic operation:

The equipment features an automatic needle protection device that automatically lifts the needle when it strikes a hard object, preventing damage. The entire machine is constructed of SUS304 stainless steel, meeting food hygiene standards. Components such as the conveyor belt are rationally designed and easy to clean.
