What is the purpose of the rake in an industrial thickener?

Raking plays a major role in transporting solids to the underflow discharge point and increasing the solids concentration in a thickener or clarifier.

What is the purpose of a thickener?

A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.

How does a thickener operate?

Thickeners are mechanically continuous process equipment which operates on a particle/floccule sedimentation principle where in simplest terms the solids settle to the bottom of the thickener tank and the water overflows the tank.

What is Torque in thickener?

Torque is nothing more than a rotary force being applied from the rake arms to the drive shaft. It is the degree of torque that indicates to the operator the load that is in the thickener and when the rake arms have to be lifted.

What is thickener rise rate?

Rise rate parametrizes the area required to recover the design flow or solids loading, the design dry tonnage. In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput.

What are the different types of thickening agents?

66 Types of Thickening Agents.

  • Cornstarch. Cornstarch is the most common thickening agent used in the industry.
  • Pre-gelatinized Starches. Pre-gelatinized starches are mixed with sugar and then added to the water or juice.
  • Arrowroot.
  • Agar-Agar.
  • Algin (Sodium Alginate)
  • Gelatin.
  • Gum Arabic or Acacia.
  • What are examples of thickening agents?

    Here is a list of the most common starch and gum food thickeners.

    • Wheat Flour. Wheat flour is the thickening agent to make a roux.
    • Cornstarch. The corn endosperm is ground, washed, dried to a fine powder.
    • Arrowroot.
    • Tapioca Starch.
    • Xanthan Gum.

    What is a high rate thickener?

    High-Rate Thickeners provide immediately reuseable process water and recover approximately 85% of the water from an effluent feed. This high level of water recovery keeps water consumption at sustainable levels, as well as drastically reduces the slurry volume reporting to waste ponds.

    What is thickener underflow?

    Concentrate Slurry, Abrasive materials from three areas including very abrasive high grade nickel concentrate, mixture of copper and nickel and copper slurry with low nickel, flows up to 22 m3/h, up to 72% solids solids density of 4.29 – 4.97. …

    What is bed level in thickener?

    Bed level is a frequently installed instrument and can be installed and serviced during normal thickener operation. Instruments measure the height of the interface between thickened slurry at the bottom of the thickener and the clarified liquor at the top.

    What is the healthiest thickener?

    Here are the results:

    1. Irish Moss Seaweed, Best Thickener!
    2. Agar agar – Second Prize goes to Agar.
    3. Arrowroot – Third prize!
    4. Kudzu – An excellent thickener.
    5. Chia Seeds – An excellent thickener.
    6. Flaxseed Meal – Very good, viscous holding power.
    7. Potato Starch – A good thickener.
    8. Cornstarch – A good thickener.

    What can I substitute for flour for thickening?

    Cornstarch or arrowroot Cornstarch and arrowroot are gluten-free alternatives to thickening with flour. They’ll also keep your sauce clear and cloud-free. You’ll need about 1 tablespoon for every cup of liquid in the recipe. Mix the cornstarch with equal parts water to create a slurry and pour it into the pot.
