The Crenova VS100S is an external vacuum machine designed for home use. Its principle is based on a pump that extracts air from a textured bag before thermally sealing the opening, which slows down the oxidation of food and extends its shelf life in the refrigerator or freezer.
Textured bags and compatibility: what the Crenova VS100S requires to operate
External suction machines like the VS100S only work with textured bags. These bags have micro-channels on their inner surface, allowing air to flow to the suction nozzle during the vacuum sealing cycle.

A smooth bag, like those used with professional chamber machines, does not allow air to escape properly. The result: incomplete suction, poor packaging adherence to the food, and a less reliable seal. Before purchasing consumables, checking for the mention “textured” or “embossed” on the bag packaging is essential.
The sealing bar width of the VS100S accommodates standard-sized bags. Cut rolls offer more flexibility than pre-cut bags, as they allow you to adjust the length to the actual volume of the food, reducing film waste.

Suction and sealing of the Crenova VS100S: performance on dry foods
On dry foods (dehydrated vegetables, cereals, cut and dried meats, hard cheeses), the VS100S performs its role effortlessly. The suction cycle lasts a few seconds, the pump extracts enough air for the bag to conform to the shape of the food, and the thermal sealing creates an airtight seal across the entire width of the bag.
The suction power is suitable for regular home use: preparing meat portions for the week, packaging cooled meal leftovers, or storing blanched vegetables before freezing. For this type of use, the machine shows no notable weaknesses.
The “pulse” mode for delicate foods
The VS100S features a manual mode (sometimes called “pulse”) that allows control over the suction duration. This mode is used for crushable foods (bread, chips, ripe fruits) where complete suction would deform the contents. The user presses the button, releases it when the desired vacuum level is reached, and then triggers the sealing.
Moist foods and portion chaining: the concrete limits of the VS100S
Difficulties arise as soon as you move outside the realm of dry foods. External suction machines like the VS100S suck air through a nozzle located at the sealing area. Any liquid present in the bag rises towards this nozzle during suction, which poses two concrete problems.
- The liquid reaches the sealing area and prevents the thermal seal from forming correctly, compromising the airtightness of the bag.
- The liquid can enter the suction mechanism and damage the pump in the medium term, a defect that warranties rarely cover.
- To circumvent the problem, the classic method is to freeze the liquid before suctioning, which significantly extends preparation time.
This constraint is particularly burdensome when preparing multiple portions of saucy dishes, marinades, or soups in a batch cooking approach. Each bag containing liquid requires prior freezing time, and the machine must cool between cycles to avoid overheating the sealing bar.
Chaining bags: the resting time factor
Entry-level external suction machines are not designed for continuous operation. After a series of five to ten bags, the sealing bar and motor heat up. The quality of the seal deteriorates, and a resting time of several minutes becomes necessary.
For a household preparing its meals for the week in a single session, this means an hour or more of packaging for about ten portions. Professional chamber machines, which are significantly more expensive, handle liquids and continuous operation without this type of limitation.
Vacuum reheating and low-temperature cooking: a nuanced expanded use
One of the uses gaining popularity for vacuum-packaged dishes is reheating in a controlled hot water bath. The principle: immerse the sealed bag in water maintained at a stable temperature to reheat the dish without altering its texture or flavors. This method, derived from low-temperature sous vide cooking, transforms the packing machine into a meal prep tool.
The VS100S can certainly be used to package dishes intended for this type of reheating, provided that the food is cooled and degreased before vacuum sealing. Textured bags generally withstand moderate reheating temperatures.
However, for true sous vide cooking (like prolonged low-temperature cooking), the quality of the seal becomes critical. An imperfect seal, weakened by too rapid a succession of cycles or by a trace of liquid, can fail during cooking. Systematically checking the airtightness of the bag before immersion prevents finding a dish drowned in the bath.
Crenova VS100S: for which user profile
The VS100S is aimed at home use focused on preserving dry or slightly moist foods, with occasional vacuum sealing sessions rather than marathon packaging. Its quality-price ratio makes it accessible for discovering the technique without investing in professional equipment.
- Suitable for: portioning meat, freezing blanched vegetables, protecting dry foods, packaging cooled dishes for later reheating.
- Less suitable for: large quantities of saucy dishes, liquid marinades, sessions of more than ten consecutive bags.
- Alternative to consider: chamber machines, which natively handle liquids, but whose price and bulk reserve them for semi-professional use.
The choice depends on the volume and type of food to be packaged each week. For a household that vacuum seals three to five bags of meat or vegetables per session, the Crenova VS100S does the job without extra cost. As soon as liquids and large batches come into play, its mechanical limits steer you towards a higher range.
