Plotter Racks use SWEP evaporators to create innovative CO2 cooling solutions for bread production

Bread is a culinary delight that wins the hearts of many Brazilians every day. In Brazil, bread is more than just a food, it is a huge part of the the culture. SWEP brazed plate heat exchangers in Plotter Racks installations use a CO2 solution to boost efficiency in the bread manufacturing process.

An energy-efficient solution for the bread industry 

Between 2019 and 2023, the number of Brazilian bakeries increased from 240,000 to 295,000, reaching a new record. According to Sindipan-MT, 76% of Brazilians eat traditional bread for breakfast every day, and the Brazilian Association of the Bakery and Confectionery Industry (ABIP) states more than 70,000 bakeries are spread across Brazil. In 2021, the bakery and confectionery market had revenues of R$105.85 billion ($20 billion USD) in the country, a growth of 15.3% compared to 2020. Based on these numbers, it is proven that bread is not only an essential staple for Brazilian families, it’s a significant part of the economy.

Plotter Racks produces solutions for this segment that are aimed at energy efficiency. In some cases, the solutions reduce electricity consumption for bread manufacturers by up to 14%. The installations use the natural refrigerant fluid CO2 and propylene glycol, significantly reducing installation costs and environmental impact due to the use of fluids that do not impact global warming.

Plotter Racks' solutions with SWEP evaporators

The Plotter Rack’s CHILL PACK and SKYRACK product lines present ideal solutions for refrigeration in the bakery industry, serving dough cooling lines, production lines, air conditioning, freezing tunnels, and frozen chambers. SWEP´s brazed plate heat exchangers have all the vital qualities demanded by the process industry for various applications and cover a wide range of applications in the food and beverage industry. In production environments with consistently high volumes and automated processing around the clock, robust and compact heat exchangers become essential to offer excellent operational performance, minimal maintenance, and a long lifespan – making SWEP the perfect heat transfer partner in this solution. The SWEP V400T and V280AS models are utilized in the SKYRACKS product line, while the SWEP DP300 range is used in the CHILL PACK product line.
