Cold Chain Logistics

Cold Chain Logistics

Effective cold chain logistics are essential to keep fruit fresh, flowers from wilting, and various chemicals and pharmaceuticals  safe during transit. In all modes of cold chain transport, temperature sensitive products are susceptible to a loss of quality.

The Global Cold Chain

Globally, there is a heightened interest in healthy food. Consumers are looking for higher-end products, such as Alaskan salmon, that must travel long distances and move quickly to ensure freshness and quality.

“Demand for fresh food is growing, and that requires increased innovation to overcome capacity and infrastructure constraints, and mitigate disruption risks to ensure quality delivery,” adds Tim Smith, executive vice president, sales and business development, for Lineage Logistics. Adjusting to these new demands while maintaining prices, places added pressure on every element of the supply chain.

Maintaining control of products is a major concern for many shippers.

Cold Chain Must Maintain Quality

In the food industry, there is an increased focus on quality, health, and integrity. Cold chain logistics must ensure that changes in texture and taste do not occur.  When a shipment strays outside recommended temperatures, quality will deteriorate rapidly.   

More premium products with a shorter shelf life and greater sensitivity to temperature, are raising the bar for temperature control and cold chain logistics.  Refrigerated warehouses across the food cold chain must maintain as many as five different temperature zones.

Cold Chain Logistics with Powerblanket

Powerblanket offers innovative cold chain solutions that will meet the demands of unique temperatures during transit. With the new Powerblanket ICE industrial cold chain solutions, you can efficiently regulate temperature-sensitive material under both regular and hot conditions. Transporting food, chemicals, and other heat sensitive materials is no longer a major challenge.

Cold Chain Logistic Options

Icepack Blanket

  • Insulated, ensuring that your ice packs will last longer than ice alone and longer than other non-insulated options on the market
  • Internal pockets place the ice directly against the surface of your container

  • An affordable option for cold chain logistics
  • Easily portable solution
  • Temperature adjusted by the number of ice packs used

Circulation Blanket

The Powerblanket Ice Circulation Blanket, a more advanced cooling solution, is combined with either a cooler or chiller to achieve optimum results. The Circulation Blanket draws heat away from the contents of the container and consistently circulates cool.

Blanket with Cooler

  • Surround your product in constant cool as ice cold water from the cooler is pumped through the blanket
  • Maintain a minimum temperature of 32°F/0°C or lower the temperature with salt or other freeze point modifiers.  
  • Forty pounds of ice can maintain the temperature of the product at 55°F/13°C for nine to ten hours in 100°F/38°C ambient temperatures
  • Operates on 12VDC or 120VAC power.  

Blanket with Chiller

  • Achieve colder and continuous results
  • Maintain industrial cooling of 20°F/-7°C
  • One chiller can operate with two 55-gallon drum blankets
  • Ideal for process cooling and other industrial cooling applications

 

Technology and Cold Chain Logistics

Like all supply chains, cold chain operators must continually upgrade technology to ensure efficiency, integrity, and safety. This includes both back-end IT infrastructure and front-end devices that gather and report key data in real time.

Some shippers use removable sensors to independently track the temperature of cold cargo, usually for high-value goods and international shipments.

 

There is a sincere need for products that can can analyze and deliver data where and when it’s needed. Powerblanket has partnered with Beacon Controls to create a solution that is effective, reliable, and on the cutting edge of real-time smart temperature monitoring.

Smart Cold Chain Temperature Monitoring with Beacon

  • Change settings locally or connect remotely through Wi-Fi or Cellular networks, so you can keep your operation running smoothly wherever you are.
  • Customize scheduling and alerts based on temperature, electrical current, voltage, and resistance readings
  • Enjoy peace of mind for cold chain logistics
  • Compatible with a wide variety of cooling or heating devices
  • Create multiple users with varying levels of access and control for added security.
  • 120/208/240V AC options, switch up to 24 amps

How long does concrete take to set

How long does concrete take to set?

If you really want to know the truth, concrete never stops curing; it continually hardens forever.  However, for practical purposes, it reaches a point where further hardening will be so slow it becomes unnoticeable.  In this article, we cover the basics of what you need to know about “how long does concrete take to set.”

 

Concrete Never Stops Curinghow long does it take concrete to set

The continual hardening occurs because cement particles react with the water in the mix (hydration), and as long as cement is in contact with moisture, even miniscule bubbles, it will continue to form bonds.  This is minimal after “full strength” is achieved, but it is continual.  

 

Curing Time for Concrete

In standard industrial cases, full strength concrete is recognized at 28 days.  At seven days, you should have concrete that is cured to 70% full strength or greater.  But to answer the question of, “How long does concrete take to set?”, concrete setting time is generally 24 to 48 hours.  At this point the neighborhood dog will not leave his footprints in it, but you should keep it clear of heavy equipment during this time period. Most mixes are cured at 28 days.

 

Factors Affecting Concrete Setting Time

  • Moisture plays a critical role in curing time for concrete.  If there is not sufficient water in the mix, the concrete will cure too fast, resulting in weaker overall strength.  Too much moisture, often used in the finishing step will weaken the top layer and cause flaking.
  • Hot ambient temperatures and wind accelerate the evaporation of moisture–speeding concrete setting time.
  • The mix design has a lot to do with concrete setting time.  Some jobs will require accelerants because the area needs to be usable as soon as possible.  The accelerant will do its job and speed up the concrete setting time.  Accelerant mixes will show a weaker overall strength in the end, but will still meet strength requirements.

 

Powerblanket Concrete Blankets

If you are wondering about how long does concrete take to set, Powerblanket has a solution for your concrete setting needs.  If you are dealing with HOT conditions and your concrete setting too quickly, consider Powerblanket ICE.

Powerblanket ICE is portable cooling equipment that will keep newly poured concrete safe from heat, regulating concrete setting time in both regular and hot conditions.

The Powerblanket ICE Circulation Blanket is combined with either a cooler or chiller to achieve optimum results. The Circulation Blanket draws heat to the blanket in order to cool the concrete.

  • Use Powerblanket’s patented heat-spreading technology in reverse–the cooling blanket draws heat away and lowers the temperature of the concrete.
  • Take it with you on every jog.  It is easily portable.
  • Blanket cover and insulation are the same as the robust system used in Powerblanket heating products
  • Control the curing speed of newly poured concrete even in hot conditions

If conditions are cold, Powerblanket concrete curing blankets provide a manageable way to cure concrete effectively and confidently. Powerblanket curing blankets increase production by rapidly curing with consistent, even heat.

  •  Cure concrete 2.8 times faster than conventional, insulated blankets
  •  Maintain moisture throughout hydrating process
  •  Easily installed and removed
  •  Produce cold weather concreting strength of up to 3,925 psi in 72 hours
  •  Prevent a freeze cycle
  •  Thaw ground and frost from job site before you pour
  •  Reduce downtime & increase profitability
  •  Maintain ACI compliance for cold weather concreting
