Vane-Type Vacuum Filling Machine ZKG-6500 – 3,500 kg/h Large-Chunk Sausage Filler

Сипаттама

Product Overview

The Vane-Type Vacuum Filling Machine ZKG-6500 by Ever Power ет өңдеу жабдықтары компаниясы is a high-capacity servo-driven vacuum filler purpose-built for large-piece meat products — sausage products containing whole-muscle chunks of 3–5 cm, egg sausage, meat paste rolls, and coarse-texture formulations that standard vane fillers struggle to handle without tearing. Where conventional fillers shred large inclusions or jam on fibrous material, the ZKG-6500’s uniquely designed internal feed path and 12-vane pump geometry preserve chunk integrity throughout the fill cycle, delivering product to the stuffer horn with texture and appearance intact.

At a rated production capacity of 3,500 kg/h, the ZKG-6500 is one of the highest-throughput single-machine vacuum fillers available for mid-to-large processing lines. The main motor delivers 3 kW as part of a 7 kW total installed power package (main motor + ancillary drives). A German Busch vacuum pump maintains continuous negative pressure in the product chamber, suppressing air entrainment, oxidation, and the bacterial growth associated with air pockets — extending shelf life without sacrificing throughput speed.

Portion control is handled by a German Siemens servo drive system paired with a Siemens touchscreen HMI, delivering stepless speed regulation from 0–600 portions per minute and portion weight accuracy across a range of 5 g to 999,999 g — making the ZKG-6500 equally suited to small cocktail sausages and large-diameter whole-muscle rolls. A 220 L standard hopper feeds the pump continuously, while the optional high-speed portion controller and automatic hanging system allow the machine to serve as the anchor unit of a complete automated sausage line.

The entire product-contact structure is SUS304 stainless steel with a special polished surface finish, and all electrical components — including Eaton manual switches and SKF Sweden bearings — are imported internationally-branded parts selected for long service intervals and low failure rates. A filtered cooling circuit keeps internal components at stable operating temperature, and the pump body cover includes a protective guard as standard. Compatible with double-clipping machines for a fully integrated fill-and-clip line.

Performance & Engineering Notes

Why 12 Vanes?

The ZKG-6500 uses a 12-vane pump configuration rather than the 8- or 10-vane layouts common in smaller fillers. More vanes means smaller swept volume per vane cell — each portioning event moves a smaller parcel of product, reducing the peak shear force applied to large meat chunks at any single moment. The result is lower mechanical stress on inclusions at 3,500 kg/h throughput. The vanes and impeller are heat-treated using internationally sourced materials, providing wear resistance needed for continuous industrial operation over multiple shifts without replacement.

Vacuum Filling vs. Atmospheric Filling

Vacuum filling is not simply a feature — for fresh-meat and high-fat products it is a shelf-life requirement. Air pockets within a filled sausage accelerate lipid oxidation (rancidity), support aerobic bacterial growth, and create grey discolouration rings visible when the product is sliced. The German Busch vacuum pump in the ZKG-6500 maintains consistent chamber vacuum throughout the filling cycle, including during hopper refill transitions. The filtered cooling system protects the pump from heat generated during sustained high-capacity operation — an important reliability factor for three-shift production environments.

Main Shaft Sealing

The ZKG-6500 uses a German-quality oil seal on the main shaft — a specification detail that determines long-term reliability in a fat-laden product environment. Inadequate shaft sealing allows product fat to migrate into the gearbox, contaminating lubricant and accelerating bearing wear. The imported oil seal prevents this ingress, supporting extended maintenance intervals even when processing high-fat formulations at maximum speed.

ZKG-6500 vs. YZG-6000 — Choosing the Right Model

Both the ZKG-6500 and the YZG-6000 are vane-type vacuum fillers, but they address different production requirements. The ZKG-6500 is the larger-capacity model (3,500 kg/h vs. the YZG-6000’s lower range), and its 12-vane pump geometry is specifically optimised for large-chunk products where preserving inclusion size is the priority. The YZG-6000 is suited to fine-emulsion and standard sausage formulations where portion accuracy at moderate throughput is the primary need. For processors running a mixed product range — large-chunk sausage alongside fine frankfurter — the ZKG-6500 handles both, while the YZG-6000 may be preferred as a dedicated precision filler for smaller batches.

Integration with Downstream Equipment

The ZKG-6500’s stepless 0–600 portions/min filling speed makes it synchronisable with a wide range of downstream clipping, kinking, and hanging machines. The optional automatic hanging system extends the machine’s capability to include a complete fill-hang sequence without manual operator intervention between stations. For processors already running the YZG-1200 High-Speed Kinking Machine or an aluminium wire clipping machine, the ZKG-6500 is the natural choice for the upstream filler: its speed range fully encompasses the downstream machine’s maximum throughput, eliminating the ZKG-6500 as the line bottleneck.
