Gunther Needle Injector

• Curing and marinating of meat products such as bacon, ham, and poultry.
• Enhancing flavour and moisture content in various protein items.
• Injecting brine or marinades into fish fillets and whole fish.
• Applying solutions to cheese for flavour or preservation.
• Introducing tenderising agents into red meats.

Typical throughput

For this class of equipment, throughput commonly ranges from 500 kg/hr to 3,000 kg/hr, depending on product size and injection percentage.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz.

Injection pressure

Adjustable injection pressures are standard, typically ranging from 0.5 to 4.0 bar.

Needle configuration

Units similar to the PI 52 commonly feature multiple independent needles, allowing for precise and consistent injection across the product.

Construction material

All food-contact parts and the main frame are typically constructed from stainless steel for hygiene and durability.

Product dimensions

This type of injector is generally suitable for products up to 250mm in height, with varying widths depending on the conveyor belt.

Filtration system

A rotary or multi-stage filtration system is commonly integrated to ensure brine cleanliness and prevent needle blockages.

Control system

Modern units typically feature a PLC-based control system with a touchscreen interface for setting parameters.

• What maintenance is typically required for a needle injector?

  Regular cleaning of the brine system, inspection and replacement of worn needles, and checking pump seals are standard maintenance tasks. The rotary filter also requires periodic cleaning.

• Can this injector handle different types of brine?

• Is it possible to adjust the injection percentage?

• What safety features are commonly found on these machines?

• How difficult is it to change needles?

• What is the typical footprint of a Gunther PI 52 injector?

Injecting and filling equipment holds strong reputation among food processors for consistent portion control and product uniformity. Buyers typically prioritise machines with robust construction, reliable pump systems, and compatibility with existing production lines. Used units should be inspected for wear on seals, nozzles and calibration accuracy. Industry sentiment favours models offering straightforward maintenance and flexibility across different product viscosities. Build quality and documented service history substantially influence purchasing decisions, with preference for established manufacturers known for durability and spare parts availability.
