Ningbo Zhengguang Food Machinery Co., Ltd.
Ningbo Zhengguang Food Machinery Co., Ltd. operates in Xiangshan and designs, builds and engineers food pretreatment lines. Its catalogue covers conveying and lifting, grading and sorting, washing, cutting, blanching, dewatering and drying, thermal processing, canned-food lines and beverage lines. On the packaging side it also makes the ZGXD150, a depalletizer that unloads empty cans at the head of a can line. Zhengguang suits processors who want fruit and vegetable preparation and canning equipment from one engineering supplier. [1][2]

SECTION 01
What Zhengguang makes
Zhengguang describes itself as a design, manufacturing and engineering business for food pretreatment. Most of its range handles the food itself. A smaller part handles containers, such as the empty cans that feed a filler. [1]
Start your inquiry by naming what the machine will touch. Washing vegetables, heat-treating food and unloading empty cans each call for a different specification, and machines from one catalogue are built for different jobs.
Swipe or scroll the table to compare all columns.
| Product area | What you tell Zhengguang | Point to settle early |
|---|---|---|
| Fruit and vegetable preparation | Raw material, its condition on arrival and the treatment you need | Food handling and container handling use different machines |
| Conveying and lifting | Material or load, its geometry and the machines on each side | Conveyor speed and finished-pack output are separate numbers |
| Canned-food and beverage lines | Product, container and the operations you want | Ask for the module list behind the line name |
| Depalletizing and palletizing | Whether containers arrive empty or filled, and the pallet pattern | Unloading empty cans happens at the opposite end of the line from stacking finished cases |
SECTION 02
The ZGXD150 empty-can depalletizer
The ZGXD150 product page names the machine as an empty-can depalletizer. That puts it upstream of can filling, feeding empty containers into the line, well before any finished goods reach dispatch. [2]
The page gives the model name and its empty-can duty, without a table for rate, pallet size, load height or can size. Read 150 as part of the model name and ask Zhengguang for a dated rating. [2]
To get a usable offer, send your can and pallet drawings with the layer pattern, separator details and the conveyor the depalletizer must feed. Ask what happens to layer pads and empty pallets and which handling devices are in the price.
SECTION 03
Who builds what
Ask which offered machines Zhengguang designs and assembles at its Xiangshan site, which modules it buys in, and who takes responsibility for final integration. For food-processing equipment, request the material, cleaning and testing documents for your process. For can handling, request the mechanical, control and guarding documents for the build you are quoted.
SECTION 04
Fitting the depalletizer to your line
Define the condition of incoming pallets and the can rate you need at the discharge. Ask Zhengguang how the machine deals with unstable layers, part pallets, damaged cans and a blocked conveyor downstream. A short run with the machine empty tells you little, so test it with your own cans on your own pallets.
If the order goes beyond depalletizing, ask for an equipment list and an interface table covering filling, thermal processing and downstream packing. Give each module its own acceptance test, separate from the test of the whole line.
SECTION 05
Confirm before ordering
Ask Zhengguang to confirm in writing:
- the legal entity and site that will sign and build the order;
- current certificates, with issuer, scope and validity date;
- the capacity, load envelope and utilities for the ZGXD150 as quoted;
- which operations and interfaces the quoted price includes, module by module;
- any historical, customer or output figures you plan to rely on, matched to the current build.

SECTION 07
Buyer questions
Is the ZGXD150 a palletizer for finished cases?
No. Zhengguang lists it as an empty-can depalletizer, which works at the start of a can line. [2]
Does 150 mean 150 cans a minute?
The number is part of the model name. Ask Zhengguang for a written rate based on your can and pallet.
Will a Zhengguang canning line come as a complete project?
Only for the operations named in the offer. List every process step and interface you expect, and ask Zhengguang to price each one. [1]
