Bakery & Dried Foods

Using cryogenic gases to optimise ingredient handling, mixing, forming, cutting and packaging so bakers can maximise product quality, production volumes and overall efficiency

Supply

Here at BOC, we deliver chilling and freezing solutions that leverage the cryogenic cooling power of nitrogen (N₂) and carbon dioxide (CO₂) to help you raise the quality, productivity and overall efficiency of your bakery operations. Precise and continuous temperature control during both ingredient storage and mixing is one of the most effective ways to avoid oxidation, rancidity, chemical breakdown and clumping.

Proof is in the pudding

Our products help you achieve this by chilling dry ingredients such as flour, sweetener, shortening and yeast prior to mixing. Our chilling solutions also inject N₂ or CO₂ directly into the mixing bowl for more effective cooling results and repeatable batch-to-batch quality. Once the dough has been mixed, we then help optimise forming, portioning and cutting operations with solutions to ensure consistent chilling of the mix and individual quick freezing (IQF) of individual items. Last but not least, our crust-freeze (impingement) solutions and modified atmosphere packaging technologies simplify packaging and extend shelf-life.

Once dry and bakery goods are ready for dispatch, our cryogenic in-transit refrigeration solutions offer a number of advantages over conventional mechanical systems. These eco-friendly systems reduce your carbon footprint and noise levels, with the added bonus of cost efficiencies and ease of service.

CRYOLINE Cryogenic Freezers

Extensive lineup of cryogenic freezers with a CRYOLINE SI model particularly suited to high-volume IQF (individually quick- frozen) bakery products

ACCU-CHILL In-line Chilling Systems

ACCU-CHILL IC and ACCU-CHILL BI systems inject cryogens directly into dry bakery ingredients and into mixers/blenders for instant, reproducible results

MAPAX Packaging Solutions

Our MAPAX® mixtures for bakery are the best choice to master today’s packaging challenges facing dry food and bakery specialists

Gases

Carbon Dioxide (CO₂)

Carbon dioxide is used in Modified Atmosphere Packing (MAP) to inhibit the growth of fungi and bacteria on bread and bakery products

Liquid carbon dioxide is used in cryogenic freezing & chilling applications of bread dough and bakery products

Gas Mixtures

Nitrogen and carbon dioxide can be combined in various quantities to produce the ideal preservation gas for any food type.

Nitrogen (N₂)

Nitrogen is used in Modified Atmosphere Packing (MAP) to prevent oxidation of bread, cakes, pasta and other bakery products as well as to reduce odours

Liquid nitrogen (LIN) is used in cryogenic freezing & chilling of breads, croissants, dough and other bakery items

Nitrogen can also be used for food inerting applications

Supply

Cylinders

BOC Food Fresh cylinders and Manifolded Cylinder Pallets (MCP) have been developed for food businesses using modified atmosphere packaging (MAP).

Food Fresh cylinders can be supplied as single gases or as mixtures. Your BOC sales and technical specialist will advise on the appropriate mixing equipment, or pre-mix cylinders. Where a pre-mix gas is chosen, BOC will advise on the exact gas mixture for packing your product.

Cryospeed

BOC’s Cryospeed service gives you access to larger volumes of oxygen, nitrogen and carbon dioxide in cryogenic liquid form. These are stored in fully maintained stainless steel vacuum-insulated vessels on your site and are filled by our Cryospeed operators. Our storage vessels are set up for the pressures, flow rates and sizes appropriate to each customer. All rented vessels are fully maintained under the supply agreement with BOC.

Bulk

High gas volumes can be stored in BOC bulk cryogenic vessels. These are installed at the customer’s site, providing a continuous and secure supply of oxygen, nitrogen or carbon-dioxide. Our Customer Engineering Service (CES) designs, installs and maintains the vessel in line with customer requirements and in compliance with all the relevant regulations (such as the Pressure Systems Safety Regulations 2000). Our On-Stream service can also cover customer-owned systems.

On-site generation

For those needing generated nitrogen, the BOC Ecovar-mini range provides an on-site generation solution at a range of pressures, flow rate and purity. On-site generation requirements are assessed on a site-specific basis to ensure the resulting set-up will cater for your needs now and in the future.
