An industrial dosing machine is a long-term investment. Once installed, it shapes production, team organization, cleaning routines and product consistency for years. Defining your requirements before comparing quotes reduces the risk of costly compromises and integration issues.
The goal is to choose a machine that doses your products into your actual trays, at the required throughput and tolerance. It also needs to meet your hygiene requirements and fit into your line, today and in the future. A clear specification also makes offers easier to compare, since every quote answers the same questions.
1. Know Your Products
Texture, viscosity, particulates and temperature all affect dosing consistency. They also change how the product flows through the hopper and how much residue is left after production.
- Viscosity and flow: thin liquids, thick sauces, pastes and emulsions each call for a different feeding and dosing approach.
- Particulates and inclusions: particle size, fragility and settling affect passage sections and agitation. The machine must keep the recipe homogeneous, from the first dose to the last.
- Temperature: a cold product can thicken and flow poorly. A hot product raises questions of material compatibility, operator safety and condensation.
- Fouling and cleanability: sticky products, or those rich in protein, sugar or fat, leave more deposits, which lengthens cleaning and downtime.
Wherever possible, validate the equipment with representative samples, including your most challenging recipes. A trial on an easy product rarely proves much for a whole range.
For a food dosing machine, trials should cover the full range of products you plan to manufacture. Include seasonal recipes, upcoming launches and your most delicate product. A machine that handles your simplest recipe says little about the others.
A common mistake is to judge a machine on a single reference product. Another is to overlook how the product behaves over a full shift. Settling, temperature drift and fouling often appear after the first hour, rarely in the first minutes of a trial.
2. Define Your Throughput, Formats and Recipes
Throughput should be defined according to your trays or containers, the breadth of your recipe range and the reality of your changeovers. A machine that runs fast on one recipe and one format can slow down with frequent changeovers, different viscosities or several fill weights.
- Current and future throughput: define the output you need today, then a realistic level after growth or line upgrades.
- Formats: list every tray or container format, with dimensions, fill height, positioning constraints and tolerances.
- Recipes: count your recipes and identify those whose behavior changes, for example with viscosity, particulates, temperature or density.
- Changeovers: estimate how many you run per shift and per week. If they are frequent, prioritize recipe-driven settings, repeatability and quick access for cleaning over maximum rated speed.
To align purchasing and engineering, translate throughput into a concrete target: a number of doses per minute at the required weight or volume, including normal stoppages.
Write the dosing machine specification before talking to suppliers. Quotes then stay comparable and assumptions stay assumptions instead of turning into technical choices.
Think about people as much as machines. Changeovers depend on operators, so settings must be easy to reproduce from one shift to the next. Recipe-based control limits manual adjustments and the errors that come with them. Ask each supplier how a changeover works in practice, and how long it takes.
3. Set Your Accuracy and Hygiene Requirements
Accuracy is as much a commercial parameter as a technical one. Define the acceptable variation and put a figure on its cost in overfilling, especially for high-value formulations. Also define the underfilling risk you cannot accept, whether regulatory, customer-related or brand-related. Then choose the expected control mode: manual adjustment, recipe-based control or checkweighing with continuous correction.
Overfilling deserves a real calculation. Multiply a small excess by the number of doses per shift, then by the number of shifts per year. The result can change the way you compare two offers.
Define hygiene requirements at the same time, because a machine’s cleaning design determines its availability. A machine that meets tolerances but takes too long to clean, inspect or reassemble drags down line performance.
- Accuracy targets: set the target weight or volume, the acceptable variation and the product conditions in which it must be met.
- Cleaning procedure: specify the type of cleaning (between recipes, daily, allergen changeover, washdown or full disassembly), its frequency and the acceptable downtime.
- Hygienic design: check access to product-contact zones, retention areas, drainage, the tools required and visibility for inspection.
In practice, ask yourself what level of accuracy and hygiene the machine can sustain on your real products, with short cleaning times and reasonable effort from operators.
4. Plan the Integration Into Your Line
Integration determines whether the machine becomes a reliable link in the line or a source of disruption. Review footprint, tray handling and communication with neighboring equipment before finalizing the layout.
- Footprint and access: allow space for cleaning, maintenance, guarding, safe circulation and removal of product-contact parts, in addition to the machine itself.
- Conveying and positioning: dosing depends on stable tray presentation. Define spacing, indexing and movement constraints at the dosing point.
- Line communication: specify start and stop logic, fault handling, speed matching, recipe management and data exchange with neighboring equipment.
Involve your production, maintenance and engineering teams in this review. Each will spot constraints that appear in no quote.
Ask suppliers to review your line layout before ordering. A layout drawing or a short site visit can reveal access, height or spacing issues early, while they are still easy to solve.
What to Expect From Your Machine Manufacturer
The machine is only one part of the project. The support around it matters just as much, and it starts well before delivery.
Celtech designs and manufactures dosing machines for food manufacturers, and every project starts with your product. Before you commit, our team can run trials on your samples, so you can see how your recipe, its texture and its particulates behave on the machine.
Once your machine is built, our technicians test and calibrate it before commissioning, in our workshop or on your site. Your teams receive equipment already set up for your product and ready to start production.
Every machine is designed around your formats, your recipes and your line layout. Your operators are supported from day one for start-up, changeovers and cleaning, and our after-sales service remains available once production is running.
A manufacturer that tests, calibrates and supports turns a good machine into a reliable production tool. Want to see how your product performs? Let’s schedule a trial!
The Pre-Purchase Checklist
- Product fit: have you defined viscosity, texture, particulates and temperature conditions, then tested your most challenging recipes?
- Throughput: have you specified the number of doses per minute, today and tomorrow?
- Formats and changeovers: have you listed every tray format, the number of recipes and the realistic changeover frequency?
- Accuracy and overfilling: have you set the acceptable variation and calculated the cost of overfilling and the risk of underfilling?
- Hygiene and downtime: have you defined the cleaning procedure, the access required and the acceptable downtime?
- Integration: have you checked footprint, conveying and communication with neighboring equipment?
One last practical step is to run a trial with your own recipes and your own trays.
To request one, send samples to Celtech for analysis or contact our team.
