Pfannenberg Products Assist in Making an American Staple Summer Treat

/in , , ,

Hot dogs – a staple summer treat that brings back memories of family cookouts and baseball games. It is an American favorite summertime food! Hot dogs go through a series of complex processes that combine the ingredients into their delicious final form and Pfannenberg’s PWS Air to Water Heat Exchangers are perfect to keep things running.

Meat Processing

The first step into creating one of the most loved foods is the preparation of the meat.  The meat is cut into small pieces and is placed into a large mixer.  These mixers have chopping blades to further cut the meat into smaller sizes. Here the raw ingredients and flavorings are added.  All are mixed until the mixture is a smooth paste consistency. Processes like this can require large control panels to operate the system and Pfannenberg’s PWS Air To Water Heat Exchangers are ideal for cooling your electrical components. Pfannenberg’s Air/Water Heat Exchangers utilizes chilled water, that is readily available, and an internal fan to provide cool air to prevent critical electronics from overheating.

Linking

The paste is always going through inspections throughout the entire process. After inspection from the mixer – the mix is moved into a stuffer.  This machine will push the paste into tube casings.  The casings are twisted at measured sections to make equally sized hot dogs. There are various casings – natural or artificial. The shaping of the hot dogs we all know is now complete.

Smoking

After the stuffing and linking, the hot dogs are then moved to a smokehouse to cook under controlled conditions.  Manufacturers can control the temperature and the difference flavors that the smoking has on the hot dog by using difference smoke sources.  Average time it takes in this step is an hour.

Final Processing

Once the smoking is completed, the link casings are removed by an automatic peeler.  During this time, the hot dogs are sprayed with water to help bring down their temperature.  Then the hot dogs are then transported to be packaged. Before going into the final packaging, the hot dogs are inspected to make sure there are no foreign ingredients in the product.

Pfannenberg has experience with inspection and x-ray equipment. Pfannenberg was able to combine a Chiller and PWS Air  To Water Heat Exchanger to cool the x-ray tubes as well as the electrical enclosure as one example.

The packaging machines can process thousands of hot dogs in an hour.  They are operating at very fast speeds and require proper thermal management cooling to keep their machines up-and-running. Once packaged, hot dogs are inspected again, freshness dates are added, and they are all boxed up to be transferred to the warehouse for refrigeration until they are shipped. The entire process from start to finish, only takes a few hours.

Chillers for X-Ray Machines – A Food & Beverage Success Story

/in , , ,

With the next round of Food Safety Modernization Act (FSMA) updated regulations taking into effect September, food processing companies are scurrying to make sure their facilities are up to code. The newest set of updates will support efforts into the quick responses to food/beverage related emergencies (contamination, expired products, recalls, and foreign materials). The new amendments also require that the FDA inspect the food production facility every two years to make sure that the facility and products adhere to all regulations.

A simple first step into maintaining food processing safety is x-ray/inspection equipment for product safety and making sure the machines operate properly.  In making sure these machines operate properly, one has to make sure that they have the proper thermal management equipment; something in which Pfannenberg has extensive experience in.

Success Story

Pfannenberg worked directly with a food and beverage inspection OEM to provide complete engineering solutions for the cooling of x-ray tubes and the internal cavity of their inspection machines. These machines would end up in various food & beverage and pharmaceutical end use facilities.  Before meeting with Pfannenberg our customer used several different competing thermal management products; conventional cabinet air conditioners to cool the machine cavity, two small internal fans to move the air around and a small chiller. It was costly, cumbersome while leading to additional maintenance costs and condensate issues.

The Pfanneberg team came up with a solution to utilize a CC Chiller in conjunction with a small PWS Air to Water Heat Exchanger to cool the x-ray tubes and internal cavity.  By combining products and eliminating an air conditioning unit, the Pfannenberg option required less maintenance and was more cost effective eliminating dependencies on different competing products.

Ammonia Gas Detection in Food & Beverage Facilities

/in ,

Alarm and Warning Devices to Notify Personnel Regarding Dangerous Gas Leaks

Ammonia leaks are pretty uncommon, but when one does occur – the results could be lethal.  Ammonia gas is very toxic and flammable.  Typically ammonia can be detected by smell (a strong and pungent odor), but it is a colorless gas.

The human nose can detect an ammonia leak with exposure between 5-20 ppm. With exposure 25 – 1,000 ppm, employees with have teary eyes, difficulty breathing, and the instinct to flee the area. The time exposed and the amount of ammonia the employee(s) are exposed to, determines various effects on the human body – ranging from a slight smell to teary eyes and unable to breathe, possibly death.

There are both, caustic and hazardous versions of the chemical.  In most large scale food and beverage facilities one would find the caustic version of the chemical used to aid in refrigeration.  The chemical can also be mixed with water (ammonia hydroxide) to create a multipurpose cleaning agent. 

Majority of these leaks occur in the mechanical room containing the refrigeration compressors of the facility.  Most ammonia used within a plant is used for refrigeration.  Why do so many food and beverage manufacturers use ammonia refrigeration in their facilities when it is potentially dangerous?  Ammonia refrigeration is one of the most energy efficient and cost effective ways of storing and processing food and beverage product.

Food and beverage ammonia refrigeration applications include:

  • Cooling of beverages, beer, wine
  • Freezing of process foods
  • Freezing of ice cream
  • Cooling of dairy products
  • Freezing and refrigeration of meats

Unlike fire evacuations and being told to exit to the closest door… with ammonia leaks, employees are asked to wait for specific instructions in where to exit. Sometimes the closest exit may not always be in the right direction, away from the gas leak.  Ammonia evacuation signals must be different from fire alarms to avoid confusions.  All employees must be trained on the difference in the alarms.

Pfannenberg has had experience in protecting personnel from gas and vapor leaks.  Our robust and multi-toned flashing sounders, offer 80 different tones – perfect for alerting and protecting personnel. Due to the large signaling coverage provided by each alarm, the amount of signaling devices required is significantly reduced. This supports an application that is economical while ensuring industrial safety.

Generally speaking, a blue light/strobe is a warning color used for toxic gas leaks, and red is used as a warning color for combustible gas leaks – but users can use any color unless directed by a local code or law. Blue tends to be the favorable color used in Ammonia gas leak alarms.

Common refrigeration alarms alert people about high concentrations in a room where they should not go.  Our signaling will extend this warning to other operating employees in the facility who can be immediately alerted to a problem so corrective action can be immediately undertaken.


Pfannenberg industrial alarms with visual and audible notifications come with a standard 10-Year Warranty, guaranteed in protecting man, machine, and the environment.

Using Chillers to Help Make Pasta

/in , ,

Pasta – A staple in Italian cuisine that can be found in almost every household. It is a food that carries memories and conveys emotions.

Pasta is a noodle that is made from water and flour (eggs and other ingredients can be added for various flavors) – it has a simple composition, but the process requires a lot of love and patience. Pasta is classified under two broad categories: dried and fresh – from there it is classified by various shapes, sizes, flavors and ingredients.

In the United States, there has been an increase in buying trends for ready-made meals and easy to prepare foods. Dried pasta falls under both categories, but also has a strong nutritional composition – containing various vitamins and nutrients. Pasta takes many different shapes and sizes. Making dried pasta is a delicate process, it can easily tear and get ruined.  Ingredients are first mixed, extruded and dried, then taken to be packaged and shipped – all important steps into delivering a sought-after product.

Variety of types and shapes of dry pasta

An important manufacturing step in the dried pasta making process is the use of an extruder.Pfannenbergs’ packaged chillers are an ideal solution for the temperature regulation in this process. At the extrusion phase the pasta is given it’s distinct shape and size. This is the step in the process that classifies the pasta style, from angel hair and bow tie to lasagna and spaghetti.  Depending on the type of pasta that is desired, the dough is either pushed through dies or rolled out and cut.  Many types of dried pasta are commercially reproduced through this extrusion process.

The extrusion machine can mass produce large amounts of pasta to be dried. As the pasta enters the extruder it is approximately 95 °F (35 °C). As the pasta is pressed through the extruder there is an increase in the product temperature due to the friction of the pasta being forced out. A chiller is used to cool the water jacket built within the extruder to maintain an ideal exit temperature of 115 °F (45 °C). Anything warmer than this leads to a different consistency and risk of damage to the product.

Our Pfannenberg CC chiller series are used for this extrusion process globally. It’s compact design, ease of use and durability allows for integration within the OEM equipment.

We would all love to make our own fresh pasta at home, but with today’s busy lifestyle having a box of dried pasta in your cupboard is a staple for a quick meal.  Next time you cook your pasta in a pot of hot boiling water, remember its the cooling needed in the process to help make this delicious meal possible.
