How to regulate the chocolate tempering temperature

The production of chocolate is a very delicate and complex process, which needs precise levels of temperature, to achieve a high quality product.

One of the basic steps in the processing of chocolate is tempering, that explained in very simple terms is a pre-crystallization of melting chocolate, before the modeling, so as to obtain a stable product over time, which presents a good surface gloss combined with a right internal compactness.

To obtain these results the modern tempering machines use temperature control units, providing heating / water cooling, according to a pre-determined cycle, to precise temperatures, with very narrow tolerances (0.1 ° C). These cycles change on the type of chocolate, but all need for fine regulation of temperature.

The typical tempering cycle passes through 3 stages of temperature:

  • first cooling of the chocolate mass
  • second cooling
  • post heating

The levels of temperature and time are typically between 45°C to 30/32°C and all the steps are verified with appropriate instruments which verify the grade of chocolate tempering.

Chillers -30°C in pharma industry

Recently in Tempco we’ve developed a refrigeration solution for near-cryogenic temperatures supplied to a customer in the pharma sector, aimed to cool down to -25°C the reactor employed in the production of the active ingredient of an innovative aerosol.

After a careful evaluation of the overall process, we came with the proposition of two alternative solutions:

  • A liquid nitrogen cooling system
  • A classic compressor chillers solution

The solution using chillers was the preferred one, due to its technical advantages and the easier management. We agreed with the customer to develop a system employing two chillers working in parallel, each one achieving 75% of the total duty required.
The cooling capacity of each chiller is -30°C, and an automatic regulation system of the condensation ensures the best process efficiency in every season, an essential requirement because the plant is always operating.

The full stainless realization steel has a special insulation for extreme low temperatures. A storage and distributing skid was built inside the building of the customer, providing the reactor the non-freezing solution, and equipped with:

  • Storage tanks
  • Redundant pumps
  • Monitoring and management centralized system

The remote management from a control-room allows monitoring and piloting of both chillers and pumps, with the possibility to manage alarms in order to ensure maximum productivity and to avoid expensive downtimes.

How to control the temperature in the calender rolls

There are a lot of continuous production processes, using rotating cylinders for the most disparate functions:

  • hot pressing
  • gravure
  • packaging films
  • modeling (embossing, flocking etc …)
  • plastic or rubber molding
  • refinement of food or pharmaceutical products
  • Heating / cooling of films or products to make flakes

generically we call them calender rolls.

How to…cooling down engines in aggressive environment

Typically engines radiators installed on cogeneration biogas plants sustain the worst conditions, due to an aggressive and corrosive environment.

Tempco made radiators and free coolers for many different application fields… and we know the above issue as well.

Related to these installation we make special radiators with:

  • stainless steel pipes
  • aluminium epoxy coated fins

The structure can be made of galvanized steel or stainless steel to achieve the best resistance in those aggressive environments.

Blowers are made with blades and engines treated with anti-corrosion protection.

For petrochemical, pharma and chemical field of applications we also make radiators ATEX certified.

Contact us directly via email at info@tempco.it for more details on these special applications.

Smart energy TREG HCE

When a new year begins, it is usually time to focus on new targets and new goals.

I reviewed the last twelve months and I realised how many new ambitious and interesting projects we have developed as part of the Tempco team.

One of the products we are very proud of are our special temperature control units. Precisely because this is an entirely non-standard product, except for the approach and the method we use to check customer data, analyse it and find the best outcome for them to streamline production and ensure it is more efficient.

In 2017 we will increasingly focus on customising our temperature control units:

  • remote communication of operating data
  • accurate temperature control, both in terms of heating and cooling
  • heating capacity modulation
  • energy savings

these are some of the points we focused on and for which everyone in our work group improved their knowledge.

Have a nice day!

Frost-Protection and Heat exchange

Winter’s freezing cold is insidious to cooling plants, heat exchangers and free coolers, exposed to the danger of severe and costly damages and bursts, leading to unexpected productive stops.

Tempco’s monoethylene glycol based fluid T Unfreeze ensures excellent frost-protection, as well as long-lasting corrosion protection for maximum heat transfer efficiency.

Have you already provided your plants the proper protection against the incoming cold season?

 

Cooling towers, first European efficiency standard

The collaboration between industries and the independent certification association Eurovent Certita Certification (ECC) led on last October to the publication of the first European thermal performance efficiency standard for cooling towers.

The Eurovent 9/12 standard has been developed during the last 14 months and is the result of the joint effort of 10 of the main European cooling towers manufacturers within the Eurovent Product Group Evaporative Cooling Equipment (PG-CT). Eurovent 9/12 sets minimum energy efficiency targets for mechanical draught evaporative cooling products, including:

Open wet cooling towers
Closed-circuit cooling towers
Evaporative condensers (both in forced and induced draught configuration)

Hard anodic oxidation of aluminium – 2

A few days ago, I wrote an article on the anodic oxidation of aluminium for the purpose outlined above, to improve the characteristics of the metal and adapt it to applications in diverse areas and environments, exploiting its properties of lightness.

Zolder, Belgium - April 21, 2013: Brembo disc brake on a AF Corse Ferrari 458 Italia GT3 race car in the pit lane before the race. The car is participating in the 2013 FIA GT championship.

There is a process of hard anodic oxidation that best exploits the mechanical characteristics and makes the aluminium suited also to uses especially aggressive in terms of resistance to stress or friction.
